FIELD: television sets; generation of horizontal sync pulses. SUBSTANCE: sync pulse generator of horizontal deflection yoke has first phase-locked loop generating first clock signal at first horizontal-synchronization frequency 1fl; second phase- locked loop for receiving second clock signal and feedback signal corresponding to second frequency 2fl obtained from backtrace pulses of horizontal-deflection output stage and incorporating voltage-controlled generator for producing smoothed down and corrected signal at second frequency 2fl; and horizontal-deflection output stage connected to second phase-locked loop. EFFECT: enhanced precision of synchronization. 5 cl, 20 dwg
