Wireless remote control transmitting/receiving remote control circuit

Wireless remote control refers to the realization of non-contact remote control of controlled targets. This control technology is widely used in industrial control, aerospace, home appliances and other fields. A remote control system generally consists of a transmitter circuit and a receiver circuit. The transmitter circuit generally consists of several parts such as command keys, command encoding circuit, modulation circuit, drive circuit, and transmitting circuit; the receiver circuit generally consists of several parts such as receiving circuit, amplifying circuit, demodulation circuit, command decoding circuit, and execution circuit. composition. The following figure shows the transmitting and receiving circuit diagrams of wireless remote control respectively.
