Abstract
An acoustic remote control link transmits different value bits as pulses containing different numbers of carrier cycles and identifies those bits on reception on the basis of the received pulses containing numbers of carrier cycles in one or other of two ranges. Each word transmitted is accompanied by a word of inverse digital value, the two words being compared on reception. A received pulse is deemed to have finished when a gap of given duration exists in the carrier.
