Abstract
A television video signal control system is disclosed in which an amplitude control signal and a clamp voltage control signal digitally detected in the automatic gain control and clamp voltage control of a television signal receiver respectively are applied alternately to a single D/A converter. The resulting analog signal is sampled and held alternately at holding circuits corresponding to the two control signals. A D/A converter for converting the two control signals from digital to analog state is thus saved as compared with the prior art.
