ABSTRACT:
In an automatic kinescope bias (AKB) control system for a television receiver, a voltage representative of kinescope bias is derived from a sensing point coupled to the television signal processing channel and to AKB signal processing circuits. A switching network attenuates large white-going television signal amplitude components at the sensing point during picture information intervals, to preclude sense point voltage levels which could otherwise ultimately disrupt the operation of the AKB signal processing circuits during AKB operating intervals.
