ABSTRACT:
A system and a receiver for transmission of signals by a double sideband amplitude modulated carrier with the carrier suppressed, known as a DSBSC wave, without reinsertion of the carrier at the receiver. In the receiver the DSBSC wave is amplified, demodulated by a full-wave rectifier, and the rectifier output reversed in polarity at instants of successive zero crossings of the signal, to produce the signal free from extraneous components.
