The Timewave DSP-599zx is the latest generation DSP filter incorporating the newest high speed CPU. The extra power gives the user unparalleled features and field upgradeable for the future. The new LCD display, push buttons, and Visible Memory™ let you see the exact settings of the filter. The optical encoders give the operator continuous tuning of filters.

NOISE REDUCTION

The noise reduction functions of the DSP-599zx operate by examining a characteristic of signals and noise called correlation, and dynamically filtering out the undesired noise. The degree of correlation is relative. Random noise such as white noise or static is uncorrelated. Speech is moderately correlated. Pure tones such as heterodynes are highly correlated. The DSP-599zx measures correlation and automatically filters out noise that is outside its correlation threshold-holds.

DATA and BANDPASS FILTERS

Narrow band signals like CW an R TTY require bandpass f ilters with steep skirts and linear phase response. Linear phase response maximizes the unusable signaling rate for a given bandwidth and minimizes ringing often heard on other types of extremely sharp filters. Filter skirts are so steep that a signal literally falls off the edge of the passband as you tune through a signal. Bandwidths range from 10 Hz to 600 Hz, and center frequencies from 200 to 2150 Hz. Narrow filters are useful for trying to dig out ex-

tremely weak signals from noise and QRM. The wider filters allow easy tuning and listening to multiple CW signals simultaneously. Data filters supported in this filter are RTTY, AMTOR, PacTOR, G-TOR™, HF Packet, SSTV, WeFAX, SITOR and CLO VER. RTTY has two methods of being used in addition to regular filtering. You have a complete data modem designed for RTTY. You can use the remodulator mode that detects and regenerates the mark and space to the modem.

VERSION 5.01 ENHANCEMENTS

Timewa ve’ s DSP-599zx latest enhancements ha ve something for every operator; CW Spotlight, Binaural CW , new noise processing techniques for the phone operator and SWL community. T he PC/Radio mode allows you to explore the new sound card based implementations effortlessly .

TEST INSTRUMENTS

An added benefit of the powerful DSP processor and LCD display in the DSP-599zx is a Test Instrument mode. This mode is designed to provide the audio test instruments necessary for normal maintenance and setup of audio circuits in radio equipment installations. A low distortion audio sine wave generator and an audio millivoltmeter cover the frequency range from 20 Hz to 10 kHz. The millivoltmeter measures true rms and peak, as low as 1 mV, and the sine wave generator output is calibrated in the same units. The sine wave generator and the milli voltmeter operate simultaneously for gain and frequency response measurements.
