Abstract

In a synchronizing circuit for a television receiver including a sine wave oscillator 7, the output waveform is distorted, to produce a pulse signal which is fed to a circuit 15 for producing pulses from the peaks of the distorted waveform, and the output from this circuit is differentiated in circuit 17. The resulting signal is then fed to a comparator 6 together with the received synchronizing pulse to produce a control signal for the oscillator.
