  • Video sync validity detector
    Patent number: 4543614
    Abstract: A video sync validity detector comprises a peak detector circuit and an average detector circuit both responsive to output signals from a sync separator network. Sync representative signals are provided from the output of the peak detector. The average detector is coupled to the peak detector for inhibiting sync representative outputs therefrom in the presence of sync separator output signals representative of false sync signals of average value.
