Operating Principle

• Signal Demodulation ：

• Receiving antenna receives high-frequency signal sent by transmitter.
The signal will go through capacitive coupling, frequency-selecting circuit
to receiving demodulation unit. Finally, the demodulation module
demodulates the code signal from the radio-frequency signal of
transmitter and the code signal will be transited to MCU as control data
signal.

• MCU（Microprocessor Control Unit）

• MCU will conduct data analysis, including decoding and identification, on
the received code signal, send relevant command, output corresponding
PWM (pulse width modulation signal), so as to control the action and
operating mode of vibrator.
