Abstract
A DC coupled system for automatically controlling the high frequency peaking content of a video signal is disclosed. The system includes a DC coupled control path comprising a peak detector for developing a control voltage representative of the high frequency content of the video signal exclusive of video signal DC components, and is preceded by a video signal amplifier. A filter for shaping the frequency response of the control path is connected to the amplifier. A manually adjustable peaking control for controlling the DC bias of the amplifier is also connected to the amplifier. The filter and adjustable peaking control exhibit mutually independent operation, and are both connected to the amplifier via the same single terminal.
