摘要:
A remote control system for use in remote controlling a television receiver is provided in which a light signal is used as the remote control signal. An electroluminescent diode is used to emit the remote control light signal which is amplitudemodulated by a modulating frequency in the ultrasonic frequency range and has a very narrow band of wave lengths. The remote control system is very compact in size and completely free from the erratic operations caused by the noise.
