Abstract
Abstract A remote control device includes a transmitter (10) which is driven by a battery (E) and generates light or an ultrasonic signal, and a receiver (20) which teceives the light or the ultrasonic signal for generating a corresponding control signal. The light or the ultrasonic signal produced by the transmitter (10) is modulated in accordance with Barker series data representing the control signal. The light or the ultrasonic signal received by the receiver (20) is converted into an electric signal and is supplied to an autocorrelation function generating circuit (26).
