Abstract

A television receiver in which a microcomputer controls an operating part, and a clock generator for the microcomputer is synchronized by synchronization pulses in the television signal transmitted to the receiver. The clock generator is also in the form of a control generator for a switching network part and for the deflection stages of the television receiver. The signal from the clock generator is divided and processed by a pulse-width modulator. This pulse-width modulator emits a control signal for controlling the switching network part.
