Abstract:
A television receiver with a utility line-separated end and a controlled, line-separating, switched external power supply at the utility line end. Horizontal and vertical deflection currents are generated by horizontal and vertical output stages, and each of the two output stages are connected to a driving stage for the purpose of triggering the respective output stage. A modulator supplies a triggering signal to the driving stage and controls line separation. A horizontal frequency control signal and a vertical frequency control signal are generated and applied to horizontal and vertical sawtooth signal generators. The vertical output stage has one input connected to the horizontal sawtooth signal generator, and a second input connected to the vertical sawtooth signal generator through an error amplifier for vertical deflection of the end of the power supply connected to the utility line. The power supply is synchronized with oscillators for horizontal and vertical deflection, and is connected at the utility line-separated end.
