Abstract
An energy-dispersal signal rejection circuit adapted for use in a direct-broadcast-from-satellite system rejects an energy-dispersal signal from an input signal which includes a video signal composed with the energy-dispersal signal by generating a cancellation signal synchronized with, and having a phase and amplitude determined in accordance with the energy-dispersal signal, and such cancellation signal is composed with the input signal, for example by adding the two signals, so that the energy-dispersal signal is cancelled from the input signal and the video signal is produced as an output signal.
