Abstract :
A compatible single-sideband signal is one that permits distortion-free detection with an envelope detector and a lowpass filter. Previous work shows that it is possible to form this compatible signal using iterative preprocessing of the message waveform together with a Powers square-law s.s.b. transmitter. Weshow that the iterative preprocessing can be effectively replaced by a simple squaring circuit and lowpass filter, resulting in a low distortion system
