ABSTRACT:
In an arrangement comprising a phase control circuit the phase comparator, when receiving input pulses with which the clock pulses are in phase, will produce an output signal having a pulse frequency which is twice the pulse frequency of the input pulses. The ripple on the control-voltage for the oscillator to be controlled resulting therefrom is compensated for by adding to the output signal of the phase detector a signal which is opposite in phase to the output signal. The result is that only frequency- and phase errors produce a ripple (change) on the output signal.
