Gate pulse generating circuit and color television receiver.

摘要

A gate pulse generating circuit generates a burst gate pulse on the basis of a sync signal extracted from a video signal and then generates a gate pulse in response to the burst pulse and a flyback pulse. The gate pulse generating circuit is provided with a capacitive coupling circuit (24) and a gate pulse generator for generating a gate pulse preferentially in response to the burst gate pulse. When the burst gate pulse is not generated, the gate pulse generator (22) generates a gate pulse in response to a flyback pulse supplied through the capacitive coupling means (24).
