Abstract
A color video display signal processor comprises a source of a color difference signal and an analog to digital converter for converting the color difference signal to a digital signal. A potential divider is coupled to reference voltages of the analog to digital converter for generating a clamp voltage. A clamp arrangement is coupled to the color difference signal and to the analog to digital converter and receives the clamp reference voltage. In response to a clamp pulse the clamp arrangement couples said clamp voltage to said color difference signal.
