ABSTRACT:
An asynchronous multichannel signal processing system comprises a transmitter and a receiver. A transmitter is adapted to transmit a signal converted from data being transmitted including address data and control data such that one information unit comprises a plurality of units each including one frequency signal. The receiver is adapted to reproduce the received data by discriminating the frequency component included in the received signal. At that time, a plurality of readings of received data are reproduced in one unit time period of the transmitted signal. If and when the address data included in at least one of the plurality of readings of received data coincides with its own address data of the receiver, the control data is extracted from the received data including the coincided address data.
