Patent abstract
In a telecommunication system, channels of information are modulated onto respective carriers that are swept repeatedly across a frequency range in a time-staggered fashion so that, at any one time each carrier is at a different frequency. The carriers are multiplexed onto a single communications link and separated, on reception, by filters swept in synchronism so as to de-multiplex the signals.
