Abstract: A bistable flip-flop is set and reset respectively by two signals whose phases are to be compared and provides pulses of width determined by the phase difference. In order to prevent erroneous indication of phase synchronism when one signal frequency is an integral multiple of the other, a frequency comparator blocks the flip-flop when the frequencies are different and itself provides the said pulses, instead of the flip-flop.
