Abstract

PURPOSE: To keep the interlace under a good condition at all times for the vertical synchronous circuit in the TV receiver or the like, by securing a trigger for the vertical oscillation circuit via the signal obtained by eliminating the notch contained in the vertical synchronous signal period of the composite synchronous signal.
