INTEGRATED SYNCHRONIZING SIGNAL SEPARATING CIRCUIT FOR GENERATING A BURST GATE PULSE

摘要

The invention relates to television signal synchronisation separation circuits. An integrated circuit for separating chrominance burst gating pulses, provided for use in a digital video system, delivers a chrominance burst gating pulse signal in addition to horizontal, vertical and composite synchronisation signals. This circuit comprises in particular an inverter 12, a level-fixing circuit 13 and a chrominance burst gating pulse generator 14, which are driven by a horizontal synchronisation output circuit 6 and which deliver chrominance burst gating pulses. Application to television. <IMAGE>
