  • Phase-locked loop clock pulse extraction circuit
    Patent number: 4201948
    Abstract: A circuit for extracting a clock pulse waveform from an input pulse waveform comprising a phase-locked loop including a phase comparator having a first input to which the input pulse waveform is supplied, a second input and an output which is coupled in cascade at least with a voltage controlled oscillator whose output is coupled to the second input of the phase comparator. The clock pulse waveform is provided at the output of the oscillator.
