Abstract

PURPOSE: To obtain a good horizontal synchronizing pulse, by eliminating a virtual synchronizing false pulse and compensating the missing in horizontal synchronizing pulse.
CONSTITUTION: An output pulse HDN of a synchronizing signal separation circuit is applied to a monostable multivibrator (hereinafter MM) 301 via an AND gate 306, triggered at the trailing of the HDN and an inverted output M1 is obtained. Since this MM301 is of non-trigger type and the time constant is made shorter than the horizontal period, even if noise and equalizing pulse are applied after the horizontal synchronizing pulse, the MM is not triggered with the noise and the like. Thus, the inverting output M1 of horizontal period eliminated the noise, etc. is obtained. When the HDN is missing due to dropout, the output M2 of an MM302 falls down. The MM303 is triggered with this trailing, and missing synchronizing pulse is compensated with an output M3 obtained from the MM 302.
