Abstract
PURPOSE: To prevent jitter by delaying synchronizing signals only during a time when two or more rises (downs) of clock signals are not included and by extracting one pulse from clock signals.
CONSTITUTION: Synchronizing signals are delayed by D.FF9 only during a time when two or more rises (downs) of clock signals of a repeat frequency higher than synchronizing signals are not included, and synchronizing signals and the output signal from FF9 are applied to NAND gate 10, thereby extracting periodically the first pulse, which is generated after the rise (down) of synchronizing signals, from clock signals. This extracted pulse is outputted as a synchronizing pulse to absorb slippage of the phase of synchronizing signals, namely, slippage of the rise (down) time. Consequently, synchronizing pulses causing no jitter can be obtained.
