ABSTRACT:
A synchronizing signal processing circuit for use in a video apparatus such as a display apparatus and an information recording/reproducing is disclosed. The synchronizing signal processing circuit is capable of not only removing false synchronizing pulses included in incoming synchronizing signals and compensating for missing signals, but also causing its output to follow its input quickly after a phase of the incoming synchronizing signals has shifted abruptly.
