ABSTRACT:
An amplifier for processing television signals containing video information and related synchronizing components. An output feedback clamp circuit clamps a portion of the signal (e.g., the synchronizing components) to a point of reference potential and provides a D.C. voltage determined by the D.C. content of the video signal relative to the sync components. The amplifier is arranged to provide a predetermined D.C. gain (e.g., unity). The derived D.C. voltage is fed back to the amplifier input to reinsert a D.C. component which is processed through the amplifier in conjunction with the video signal and provides the necessary input to the clamp circuit.
