THE MANUFACTURE OF CODING REMOTE CONTROL TRANSMITTER

A special coding-and-decoding transmitting system with multichannel remote control commands is introduced in this paper.Its key circuits are the keying decoding circuit,data selector circuit,ring time-delay demarcation circuit,coding circuit,oscillating frequency demultiplier circuit,control system circuit and carrier frequency amplifier circuit.The circuits have clever designs,strong practicability and wide application range.The long-term practice has proved that the system was very stable and reliable,and accorded with the demands of technical indices in the original designs.
