ABSTRACT:
A synchronizing signal separation system for use in a recording and reproducing system is disclosed. The system comprises step of oscillating a flywheel oscillator by a synchronizing signal contained in a reproduced transformation signal thereby simultaneously generating a window pulse output and the other pulse output on the basis of the oscillated output, generating the window pulse output and the synchronizing signal as a time-base correction signal to be detected through a logical operation means, and generating the other pulse output as a signal to be detected through the logical operation means in case of lacking the synchronizing signal.
