ABSTRACT:
A wideband video signal processor includes a kinescope driver stage which is AC coupled to the kinescope, and an automatic kinescope bias (AKB) control system. During AKB operating intervals, the kinescope is energized so as to produce a cathode output pulse with a magnitude related to the level of black current conducted by the kinescope. Brightness control is achieved by coupling a brightness control voltage to a signal path which conveys the cathode output pulse to AKB signal processing circuits.
