1. Introduction
Congratulations on your purchase of the Rocktron Intellipitch™!
The Intellipitch is a 24-bit, MIDI-programmable digital effects processor featuring
intelligent, chromatic and reverse pitch shifting algorithms. In addition, the Intellipitch also
provides a host of other effects, including 8-voice stereo chorusing, three different digital
delay algorithms, unsurpassed digital reverb quality and highly flexible configuration
programming (allowing for simultaneous operation of up to 5 effects with complete
mixing capabilities). The unit also offers a fully digital implementation of patented HUSH
noise reduction at the unit’s input, as well as ducking capabilities for the delay and
reverb effects.
The Intellipitch utilizes three individual 16-bit converters and Sigma-Delta A/D
conversion, achieving a 64x oversampling rate and better than 100dB dynamic range for
superb sonic quality.
A good understanding of how the Intellipitch operates will help make designing your
own preset sounds much easier. This manual will introduce you to the Intellipitch and its
various features and functions. Please keep it for future reference.
®
Intellipitch Features
• High quality pitch shifting algorithms, including:
* 2-voice intelligent pitch shifting over 2 full octaves
* 4-voice chromatic pitch shifting over 3 full octaves
* 2-voice pitch shifting offered simultaneously with HUSH®, delay and reverb
* 2-voice reverse chromatic pitch shifting
• 8-voice chorusing with an enormous number of parameters for the richest chorus ever
• Super quiet operation through the use of high quality 16-bit converters and digital HUSH
• High purity sound due to the use of a 64X oversampling A/D converter, which samples the
signal 64 times as often as a conventional converter, and also due to the use of a separate
dual D/A converter. (Most "bargain" digital effects units use a single converter multiplexed 3 ways, resulting in decidedly higher distortion and lower dynamic range.)
• 24-bit processing and memory circuits to maintain maximum dynamic range
• Ability to store up to 8 unique MIDI controller patches with each preset
• Very high quality effects algorithms
• Highly stereo effects with panning available on almost all signals
• Built-in tuner
• Programming via knobs instead of push buttons
• Easy to read, wide viewing angle display

2. Quick Setup
When selecting a key: = sharp key
= flat key
Recalling an Intellipitch Preset
STEP 1 To recall a stored Intellipitch preset, turn the PRESET control to
the desired preset number you wish to recall. The displayed
preset will be recalled automatically.
14 PRESET TITLE
Changing Preset Parameters
STEP 1 The parameter menu for each effect can be called up via the
FUNCTION SELECT control. Turn this control to the effect to be
changed.
**** REVERB ****
STEP 2 Turn the PARAMETER SELECT control to select the parameter to
be modified.
REV DECAY 59
STEP 3 Use the PARAMETER ADJUST control to modify the parameter
value. The LED above the STORE button lights to indicate that a
parameter value has been modified from the stored preset.
REV DECAY 32
STEP 4 The COMPARE button may be used to compare the stored value to
the new one.
REV DECAY 59
Storing Modified Parameter Values
STEP 1 To store modified parameter values, press the STORE button while
viewing a parameter or effect title to begin the store procedure. The
Intellipitch will alternate displaying the current preset number/title
and:
STORE TO PRESET
STEP 2 Turn the PRESET control to select the desired preset number to
store the new parameter values into (if the new values are to be
stored into the current preset location, this step is not necessary).
User presets may be stored in preset locations 1-80. Presets 81160 are factory presets and cannot be copied over. The Intellipitch
will now alternate displaying the new preset number/title and:
STORE TO PRESET
STEP 3 Now press the STORE button a second time to store the modified
values into the selected preset location. The Intellipitch will display
"STORED" briefly before displaying the new preset number/title.
STORED
STEP 4 After the modified parameters have been stored into a new preset
location, the Intellipitch will display "COPY TITLE TOO?". This
occurs only when a new preset location is selected to store the
modified parameters into, and allows for the title from the original
preset to be copied to the new preset location as well. To copy the
title, press the STORE button a third time. The display will again
flash "STORED".
Note 1 Turn either the PRESET or FUNCTION SELECT control to exit the store
procedure without copying the title from the original preset.
Note 2 If a modified preset is exited without completing the store procedure (i.e.
"STORED" displayed at least one time), all edited parameter values will
be lost and the preset will revert to its original condition the next time it is
recalled. When saving altered parameters, always make sure the
Intellipitch flashes "STORED" at least once before exiting the preset to
ensure that the desired modifications were stored into memory.

3. Front Panel
Some of the controls on the Intellipitch front panel have more than one function, dependent
upon the mode that the unit is currently operating in. Please read this section to become familiar
with these functions.
1 POWER switch
2 CONFIG button
The CONFIG button is used to display the configuration type of the currently recalled
preset. The configuration display indicates the effects that the preset executes as well as
the order in which they are executed.
3 PRESET control
The PRESET control is used to scroll through the successive user presets and titles
stored in its memory.
4 TUNER button
The TUNER button is used to initiate a tuner function that is built into the Intellipitch.
Pressing the TUNER button a second time recalls the previous preset.
5 DISPLAY panel
6 COMPARE button
The COMPARE button may be used to compare a modified parameter value to its
stored value. (Note: When comparing an altered value to a stored value, turning a knob
or pressing a button that changes the value while the stored value is displayed will
cancel the previously modified value.)
The COMPARE button may also be used to simultaneously compare multiple modified
parameters under the same effect heading (i.e. Reverb, Mixer, etc.) to the stored values.
To do so, turn to the effect heading where the modified parameters are located and
press the COMPARE button. When the STORE LED is off, the stored parameter values
are currently active. When the STORE LED is lit, the modifed values are active.
If a knob is turned or a button is pressed which changes the effect heading when the
stored parameters are active (STORE LED off), any modified parameter values under
that heading will be lost. This is also true if a MIDI control change is received while the
stored parameters are active.
7 PARAMETER ADJUST control
This control is used to adjust the displayed parameter value. When the parameter is
changed from its original value, the LED above the STORE button will light until either
(a) the new value is stored, (b) a new preset is selected or (c) the parameter is returned
to its original value.
3
8 STORE button
This button is used to store values into the Intellipitch memory when modified. See
Chapter 8, section C, "Storing Modified Parameters" for more information.
9 PARAMETER SELECT control
When monitoring parameter values, this control will scroll through the available
parameters under the current effect heading.
In the "TITLE EDlT" function, this control will scroll through the available characters
in the title that may be edited.
10 FUNCTION SELECT control
This control allows access to each of the primary functions of the Intellipitch. Once a
specific function has been selected, the parameters for the function are accessible
through the PARAMETER SELECT control. Depending upon which configuration the
current preset is created from, these functions may include:
Mixer HUSH Reverb Delay
Ducker Voice/Delay Intelligent Shift Reverse Shift
Title Edit Controller Assign Program Mapping MIDI Channel
Factory Restore MIDI Dump/Load Tuner Config Select
11 BYPASS button
When pressed, the LED is lit and all effects are bypassed.
12 INPUT LEVEL meter
These LEDs provide visual indication of the peak level of the input signal. For the
optimal signal-to-noise ratio, it is best to adjust the input level so that the last LED
(0dB) is rarely lit. This will guard against the possibility of overdriving the unit.
13 INPUT LEVEL control
This control adjusts the unit's gain to match the signal level at the input of the
Intellipitch. The gain can be adjusted from -12dB to +12dB. Use the INPUT LEVEL
meter to determine the setting of this control.
14 CLIP L.E.D.
When lit, this L.E.D. indicates that the final analog output is being overdriven because
the Effects Level, Direct level, and Output Level control are set too high. If this occurs,
reduce these levels until this L.E.D. does not light.
15 OUTPUT LEVEL control
This control is used to adjust the output level of the unit and may be adjusted from zero
signal to a small amount of gain.
16 REFERENCE LEVEL switch
This switch determines the output range of the unit and may be set at either -10dB or
+4dB. When using professional studio equipment providing a nominal input level of
+4dB, it is recommended that the +4 setting on the Intellipitch be used for best results.
If connecting the Intellipitch to a high sensitivity input, such as the input to a guitar
amp, the -10 setting should be used.

4. Rear Panel
1 R (MONO) INPUT jack
This standard 1/4" mono jack provides input to the right channel of the Intellipitch.
When using only one input (mono), this jack should be used.
2 L INPUT jack
This standard 1/4" mono jack provides input to the left channel of the Intellipitch. When
using only one input, this jack should not be used.
3 R OUTPUT jack
This standard 1/4" mono jack provides an output for the right channel of the
Intellipitch. When using the unit in a mono application, either output jack may be used.
4 L CHANNEL OUTPUT jack
This standard 1/4" mono jack provides output for the left channel of the Intellipitch.
When using the unit in a mono application, either output jack may be used.
Note: When using a mono input (Right INPUT jack) and a mono output
(either the Left or Right OUTPUT jack), the left and right effected
signals are summed at the single output.
5 PHANTOM POWER jack
This jack provides the ability to power the Rocktron MIDI Mate™ foot controller from a
seven pin MIDI cable which connects from the MIDI Mate to the MIDI IN jack on the
rear panel of the Intellipitch, thus eliminating the need to find an AC outlet near where
the footpedal would be placed during a performance—or the need to run an extension
cord out to the MIDI Mate.
Instead of inserting the adaptor into the MIDI Mate POWER jack, plug it into the
PHANTOM POWER jack on the Intellipitch. This will power the MIDI Mate through
pins 6 and 7 of the MIDI cable connecting the two units. A 7-pin MIDI cable must be
used for this feature and is available through your Rocktron dealer.
6 MIDI IN jack
This 7-pin DIN connector receives MIDI information from the device which is
transmitting the MIDI commands for the Intellipitch to execute.
5
7 MIDI OUT/THRU jack
This standard 5-pin DIN connector passes on the MIDI information that is received at
the MIDI IN jack to other MlDI-compatible devices via a MIDI cable. It also outputs
MIDI data when performing a memory dump.
Note: Inherently in MIDI there is a limit to the number of devices which can
be chained together (series connected). With more than three devices, a
slight distortion of the MIDI signal can occur (due to signal degradation)
which can cause an error in MIDI signal transmission. Should this
problem arise, a MIDI box can be used which connects directly to the
MIDI device which transmits MIDI information and has multiple
connectors for the multiple devices receiving MIDI. MIDI cables should
not exceed 50 feet (15 meters) in length.
8 POWER jack
This jack accepts power from the 9VAC/1500mA adaptor supplied with the unit. For
more information on the power supply see the Power Requirements section on page 2.

6. Principle of Operation
The Intellipitch provides many parameters to achieve the widest variety of preset sounds possible. The parameters available for a given configuration are divided into sections accessible via the FUNCTION SELECT control.
This section will discuss each of the functions that are available which relate to a preset's overall sound. Utilitybased functions, such as MIDI operation, title editing, and factory preset restoration, are described in Chapters 8
and 9.
MIXER Function
The first function accessible when turning the FUNCTION SELECT control in any
preset is the

Mixer
function. This digital mixer allows you to control the signal levels pertain-

Caution: Digital Output overload
As the input signal enters at the unit’s input (A), the unaltered direct signal is fed
to the Direct Pre/Post HUSH Selector (B). Here you may choose for the direct
signal to remain unaltered (Pre) or feed it through the digital HUSH section (E) of
the Intellipitch (Post). Before being fed to the HUSH section, the signal must first
be converted from an analog signal to digital via the converter (D). When the
direct signal is fed to the HUSH section, it will remain digital until it is summed
together with the output of the Effects Level control (G).
It is important to remember that it is possible to overload the Digital-to-Analog
Converter (H) if the effects levels and direct signal level are set too high when
using the HUSH section with the direct signal. If this occurs, reduce these levels
until the front panel CLIP L.E.D. does not light.
Also note that when passing the direct signal through the digital HUSH (Post), a
stereo signal will be converted to mono.
Mixer Parameters
EFFECT LVL
L/R DIR LEVEL
DIRECT HUSH
This controls the level of the entire effect signal. This control should
be set relative to the levels of the Left and Right Direct signals. In
configurations which do not include a master Effects Level, the
single effect level parameter (Chorus Level, Delay Level, etc.) is
considered the master Effect Level control.
These controls allow for the left and right direct signal levels to be
set individually, thereby allowing for panning of the direct signal to
the left or right output. These controls are available in all configurations.
This determines whether the direct signal is fed through the digital
HUSH section of the Intellipitch, or bypasses it. Selecting "Post" will
pass the direct signal through the HUSH system while selecting
"Pre" will bypass this section.

stereo direct signal to mono.)

individual left and right regeneration level controls to determine the
number of times the delayed signals are repeated. Regeneration is
achieved by feeding the delayed output back into the input. Higher
levels of regeneration will result in more repeats.

The Intellipitch features
against the possibility of overloading the processor when using high
regeneration levels in configurations where a combination of
multiple voices is panned to the left or right. If the regeneration level
is set too high, the Intellipitch triggers the Regeneration Limiting and
a limit is internally set for the regeneration. This limit can not be
exceeded by increasing the

If, for example, in the
Voice 1 is panned to the left and the
maximum level, panning a second voice to the left regeneration loop
will trigger the Regeneration Limiter and reduce the regeneration to
a level such that runaway regeneration will not occur. The original
regeneration level can be reset only by recalling the preset, or, by
accessing the
it back to its original value after removing the second voice from the
regeneration loop. This feature of the Intellipitch is particularly
desirable in live situations where panning and regeneration levels
may be controlled by continuous controllers.

HUSH® Function
HUSH® is Rocktron's patented single-ended noise reduction system. The HUSH system contained in the
Intellipitch is a fully digital implementation of HUSH achieved through Digital Signal Processing (DSP), and is
modeled after the latest HUSH design.
The low level expander of the HUSH system operates like an electronic volume control. The analog design
utilizes a voltage-controlled amplifier (VCA) circuit which can control the gain between the input and output from
unity to 30, 40 or even 50dB of gain reduction. When the input signal is above the user preset threshold point, the
VCA circuit is at unity gain. This means that the amplitude of the output signal will be equal to that of the input
signal. As the input signal amplitude drops below the user preset threshold point, downward expansion begins. At
this point the expander operates like an electronic volume control and gradually begins to decrease the output
signal level relative to the input signal level. For example, if the input signal were to drop below the threshold point
by 2dB, the output would drop approximately 3dB. As the input signal drops further below the threshold point,
downward expansion increases. For example, if the input signal dropped 6dB below the threshold point, the output
level would drop by approximately 14dB. A drop in the input level by 20dB would cause the output level to drop by
approximately 54dB (i.e. 34dB of gain reduction). In the absence of any input signal, the expander will reduce the
gain such that the noise floor becomes inaudible.
HUSH® Parameters
HUSH I/O
EXP THRESH
REL RATE
This parameter simply determines whether the HUSH circuit will be in
the signal path or bypassed.
The Expander Threshold parameter determines the level at which
downward expansion begins. For example, if the expander threshold
was set at -20dB and the input signal dropped below -20dB, downward expansion would begin. Typically, this parameter should be set
between 5-20dB above the quiescent noise floor of the input signal
(i.e. if the noise floor was -60dB, a setting between -40 and -55dB will
produce the proper expansion).
The Release Rate parameter determines the amount of time required
for the downward expander to decrease the level of the output signal.
This rate is adjustable from 25mS to 800mS to accommodate a wide
variety of applications. For example, when using the expander for
gating applications on drums, a very quick release rate (25-200mS)
should be used. When used with individual instruments such as guitar,
a setting of 200mS or higher will provide adequate expansion without
being as harsh as a gate. When used with sources which have long
decay times (cymbals, etc.) a very slow release rate should be used.
12
REVERB Function
Reverb, or reverberation, is the continuance of sound within a given room or enclosed chamber after the
source of the sound has stopped producing it. More specifically, it is a multitude of echoes so densely spaced that,
to the human ear, seem as a single continuous sound. These echoes gradually decrease in intensity until they are
ultimately absorbed by the boundaries and obstacles within the room or enclosure. As the sound waves from the
signal source strike the walls or boundaries of the room, a portion of the energy is reflected away from the obstacle
and another portion is absorbed into it, thereby causing both the continuance of sound and the decaying or "dying
out" of the sound.
Reverb Types
The Intellipitch
Plate B, Room A, Room B, Hall A, Hall B, Stadium
The Plate reverb type simulates an artificial method of producing reverberation, popular
in the early years of recording, which involved using a fairly large, but very thin, metal
plate suspended at its four corners by steel wires under tension. This metal plate becomes excited by a driver unit (similar to a dynamic speaker without the diaphragm) and
the resulting reverberation is picked up by contact microphones.
The Intellipitch offers two Plate reverb types which reflect the most common plate
characteristics. This type of reverb is often used on drum and vocal tracks.
Room reverb effects simulate various rooms of different sizes and surfaces. For example, a room which is made up of primarily hardened surfaces (such as tile or hard
wood) will generate reflections containing much more high frequency information than
one which is made up of softer surfaces (such as thick carpeting). The Room reverb
effects offered by the Intellipitch can generate virtually any imaginable room setting via
highly efficient and adjustable reverb parameters.
Hall reverb simulates the reverberation characteristics of a very large room with a high
ceiling. Reflections in a hall are much longer than a typical room, as the length of time it
takes for the sound waves to travel from one surface to the next is greatly increased.
Stadium reverb simulates the characteristics of a large stadium or arena and should be
used with large amounts of predelay and high frequency damping.
HUSH; REVERB
configuration offers 8 different reverb types:
and
Dual
.
Plate A
,
Dual reverb is unique in that it allows for the left and right channels to be processed
independently one another. For example, the Predelay for the left channel can be set at
100mS while the Predelay for the right channel can be set at 200mS. This results in
reverb output from the left channel 100mS before reverb is output from the right channel.

This parameter determines the level of the reverb signal at the output
relative to the Direct signal and any other effect signals. It is accessible
from both the Mixer function and Reverb function parameter lists.
This parameter specifies the length of time that the reverb signal will
sound before it has completely faded out (or until its echoes have been
ultimately absorbed by the boundaries within the given "room"). The
maximum length of this decay will vary dependent upon which reverb
type is active.
High Frequency Damping is used to control the amount of high frequency information in the reverb signal.
This parameter determines the amount of low frequency information in
the reverb signal.
This parameter determines the current active reverb type (Room, Plate,
etc.).
This parameter allows you to pan the direct input signal to the reverb
section to the left or right - allowing for only the left or right channel to
be reverberated when used with the Dual reverb type, or, for one
channel to be reverberated to a greater degree than the other. This
parameter is adjustable from 0 to 100 - where "0" = full left, "100" = full
right and "50" = center.

HOLD TIME
This parameter determines the amount of time after a signal is input to
the Intellipitch that the left channel signal will be input to the Reverb.
Delaying the reverb signal provides greater separation of the input and
reverb signals and helps to increase the apparent size of the Room,
Hall, or Stadium.
This parameter determines the length of time after a signal is input to
the Intellipitch that the right channel signal will be input to the reverb.
Gating the reverb signal closes down the decay of the reverb very
quickly after a prescribed amount of time (most commonly a very short
period of time). This effect is often used on drums (particularly snare
drums) to produce the effect of a much fatter percussive sound. Note
that gating on the Intellipitch acts on the reverb decay, not on the
reverb output as on many other units.
This parameter determines how quickly the gate will close down the
reverb decay after the reverb has sounded for the specified time.
The Gate Threshold determines the threshold point at which gating will
take place. When the signal is below this threshold point for a period of
time, the reverb will be gated. When the input signal peak rises above
this threshold, the gate will open and reverb will be heard.
The Hold Time determines how long the reverb signal will sound before
the gate begins to close.
DELAY Function
Delay is simply a reproduction of the input signal, originating at a prescribed time (usually expressed in milliseconds, or mS) following the input signal.
Delay Types
The Intellipitch
Pong and 2-Tap.
The Stereo delay type provides two separate delays. This delay type is used for
applications requiring two discrete delay lines with individual regeneration loops.
The Ping-Pong delay type regenerates each delay’s output into the opposite delay’s
input instead of its own. This causes the delayed signals to bounce back and forth from
the left channel to the right (provided the delay outputs are panned left and right).
The 2-Tap delay type provides a single long delay line with two outputs and offers
twice the delay time of the Stereo delay type.

Delay Parameters
DELAY
MUTE TYPE
This parameter determines whether the Delay section is active
(passing a signal) or muted (not passing a signal).
This parameter allows for muting of the Delay section at its input
(Pre), its output (Post) or both.
Muting the input (Pre) of the Delay restricts any signal from entering
the delay section until the delay is switched in. When using a moderate amount of regeneration, switching out the delay with the input
muted will generate a non-delayed signal which will play over the
decaying regenerated signal which continues on after the delay is
switched out.
LEVEL
Muting the output (Post) of the delay results in the delayed signal
being immediately turned off when the delay is switched out. This
means that delays and regeneration will not continue once the delay is
switched out. If the output were
switching the delay out would be allowed to regenerate - even after
switching out the delay.
It is also possible to mute both the input and output (Both) so that no
signal enters or exits the Delay section when it is not switched in.
These are individual level controls for each of the two delays available
in the Delay section. These are not the same as the Delay Level
parameter found in the Mixer function (which adjusts the overall level
of both delay signals).

PAN
This allows for the panning of each delay to the left or right output, if
desired. The Pan parameter is adjustable from 0 to 100 - where 0 =
full left, 100 = full right and 50 = center.
DLY TIME
REGEN
D TYPE
DL HF DAMP
These parameters determine the amount of time after a signal is input
that the delayed signal will begin to reproduce the input signal.
This parameter is provided for each delay and determines the number
of times the delayed signal will repeat itself. This is achieved by
feeding the delayed output back into the input. Higher levels of
regeneration will result in more repeats.
The Delay Type parameter determines whether the Stereo, Ping-Pong
or 2-Tap delay type is currently active.
Delay High Frequency Damping determines the amount of high
frequency content in the delayed and regenerated signals. Higher
amounts of damping will result in less high frequency information in
the delayed signal.

DUCKER Function
The process of
dent upon the presence of another signal which is desired to be prominent. The Ducking feature of the Intellipitch
works in conjunction with the Delay and Reverb sections to attenuate the delay and/or reverb level while a phrase
is being played (resulting in a less cluttered, more intelligible sound), yet return each to its original level when the
phrase ends—thus allowing for the full decay of the delayed and/or reverberated signal.

RELEASE RATE
This parameter determines how much the delayed signal is attenuated
(muted). It may be set for only a slight change in signal level or it can
completely attenuate the delay/reverb signal so that no delayed or
reverberated signal passes while ducking is active.
This parameter is adjustable from .2 seconds to 9 full seconds, and
determines the length of time it takes for the muted delay signal to
return to its original signal level after the input signal falls below the
threshold point set by the Sensitivity parameter.

VOICE/DLY Function
The Voice/Dly function is available only in the following Intellipitch configurations:
HUSH;CHORUS;DELAY;REVERB
HUSH;8 VOICE CHORUS;DELAY
HUSH;PITCH SHIFT;DELAY
HUSH;PITCH SHIFT;DELAY;REVERB
In each of the above configurations, a separate Voice/Dly function is provided for each chorus or chromatic
pitch shift voice that the configuration provides—thus allowing each chorus or pitch shift voice to be configured
independently. Alternatively, any of the voices provided by a given configuration's Voice/Dly functions can be used
as a delay-only voice, either by turning the Depth parameter to "0" (in a chorus configuration) to disable the chorus
effect, or by setting the Pitch and Fine parameters to "0" (in a pitch shift configuration) to disable the pitch shift
effect.
CHORUS
The Chorus effect is achieved by using one or more delayed signals, detuning these
delayed signals (slightly changing their pitch) then
the amount of pitch detune is constantly varying. Using many delayed signals at different
delay lengths—as well as using different detune amounts, modulation rates and modulation depths for each delayed signal—results in a rich, spacious stereo chorused signal.

Chorus VOICE/DLY Parameters
LEVEL

DELAY
DEPTH
RATE
This parameter adjusts the volume of the delayed signal relative to the
other voice(s) of the effect and is included in the parameter list for
each voice (or each delay signal) of both the 8-Voice and 4-Voice
Chorus effects. (This level control is not the same as the Chorus Level
found in the Mixer function parameter list.)
The
Pan
parameter allows you to pan each voice of the chorused
signal to the left or right channel. This parameter is adjustable from 0
to 100 (where 0 = full left, 100 = full right, and 50 = center).
The
Delay
parameter determines the delay time (in milliseconds) for
each tap of the chorus signal. It is this delayed signal that is detuned
and modulated to produce the chorus effect. Using shorter delay times
for this effect produces a tighter sounding chorused signal, while using
longer delay times will achieve a much larger, ambient effect.
The
Depth
parameter adjusts the amount of modulation of each
delayed signal. A lower depth setting will produce a more subtle
detune effect while a higher setting of this control will cause a more
drastic detuning of the delayed signal.
The
Rate
parameter determines the sweep speed for the delayed
signal (i.e. the speed at which the delayed signal is modulated). A low
rate results in a slow speed and a higher rate results in a faster speed.
