ABSTRACT:
There is disclosed a synchronizing pulse generating circuit wherein a synchronization lack correcting portion (600) processes a synchronizing signal (S601) to provide a corrected synchronizing signal (S600), and a synchronizing clock generating portion (700) generates a synchronizing clock (S700) accurately synchronized with the corrected synchronizing signal (S600), and then a synchronizing pulse generating portion (800) counts the synchronizing clock (S700) to provide a synchronizing signal (S800) accurately synchronized with the synchronizing signal S601, whereby the synchronizing pulse generating circuit generates high-accuracy synchronizing pulses without exteriorly attached parts and is adapted for generation of HD pulses for use in a deflecting system of a multi-synchronization type display monitor.
