ことを特徴とする垂直同期回路。a sync separation circuit that separates a sync signal from the video detection output;
In a television receiver equipped with a circuit device that integrates the output of the sync separation circuit and applies it as a trigger voltage to the vertical oscillation circuit, the voltage obtained by integrating the sync signal taken out from the sync separation circuit is simply used as the trigger voltage. By driving a stable multi-by-break, converting it into a square wave pulse voltage and outputting it, and differentiating the pulse voltage with a capacitor and resistor, the trigger voltage of the vertical oscillation circuit is extracted from the leading edge of the pulse voltage.
