Remote control door lock circuit diagram

Amplification processor performs processing and compares it with the stored identification code. If it is correct, input the control circuit to control the actuator to work. The transmitter performs frequency shift modulation (FSK) on the frequency of the subcarrier according to the digital identification code signal, and then performs FM modulation and transmission without interference from external noise. The FM wave is received by the FM antenna of the car radio frequency modulator and enters the high frequency of the receiver ECU through the distributor.
