ABSTRACT:
An interface circuit in a kinescope bias control system includes a transistor with a base electrode coupled to the output of a kinescope drive amplifier in a television receiver, an emitter electrode coupled to a kinescope cathode, and a collector output coupled to an output circuit which provides signals to signal processing circuits. A current related to the kinescope black current level is applied to the emitter electrode. The signal gain from the base electrode to the output circuit is significantly less than the signal gain from the emitter electrode to the output circuit. Spurious signals including noise from the output of the kinescope driver are thereby significantly attenuated at the output circuit, preventing distortion of black current representative signals provided from the output circuit.
