Abstract

A circuit arrangement for synchronizing line deflection in a television receiver in which a control voltage is obtained by comparing the phase position of the received timing pulses relative to a sawtooth voltage obtained at from the line reverse pulses present in the receiver, characterized in that the amplitude of the line reverse pulses is strongly limited and that, during the time when the limited pulses take place, a capacitor is discharged and charged during the rest of the line period, so that a sawtooth voltage is produced whose average value is kept constant by controlling the charge and/or discharge current.
