In a PLL circuit comprising a voltage-controlled oscillator, a phase detector and a final control element, the final control element contains two separate channels, between the phase detector and the voltage controlled oscillator, one channel processing the useful signal components and the other channel processing the disturbance signal components of the synchronisation pulses. Each channel has two tracks, for generation of a potential difference, each track being connected to a capacitor plate.
