ABSTRACT:
A signal receiver responsive to a composite signal with video and pulse signal information includes circuitry for developing pulse signals having a width greater than the pulse signals in the composite signal and for effecting an advance in one of the developed signals with respect to one of the pulse signals of the composite signal whereby the pulse signals are removed from the composite signal to permit employment of the video information for determining the black level of a display.
