Abstract
A television receiver having a line synchronizing circuit wherein gate pulses for keying the synchronizing signal are derived from the oscillator signal, the gate pulses being positioned, by means of an auxiliary phase control loop, substantially symmetrical relative to an edge of a reference signal also derived from the oscillator signal. The auxiliary control loop also eliminates the influence of phase variations occurring in the line deflection circuit.
