Abstract
A DC coupled system for automatically controlling the high frequency peaking content of a video signal is disclosed. A peak detector develops a control voltage representative of the high frequency content of the video signal. The control voltage controls a differential control input peaking signal splitter to provide controlled amounts of complementary phased peaking signals, which are differentially combined with complimentary phased video signals to produce a controllably peaked video signal. The differential control inputs of the peaking signal splitter receive balanced quiescent bias from symmetrical bias coupling networks, one of which includes the peak detector.
