Abstract

PURPOSE: To make easy circuit integration, by reducing the dispersion in the pulse width produced from the phase relation between the horizontal synchronizing signal and the clock pulse and constituting the circuit digitally increasing the noise-proof performance using double gate circuit.
CONSTITUTION: The horizontal synchronizing signal separated from the synchronizing separation circuit taking the video signal as an input is fed to the horizontal AFC circuit 12 and the brust gate pulse generator 13, the horizontal synchronizing signal matching the phase from the circuit 12 is fed to the gate circuit 16 via the horizontal deflection circuit 14, and the logical product of the output pulse from the generator 13 is taken to produce the brust gate pulse. The circuit 13 is provided with the counter producing count pulse when a given count is made to the clock from the local chroma subcarrier generator in synchronizng with the horizontal synchronizing signal, and with the gate circuit gating the specified output of the counter. Further, timing is taken between the horizontal synchronizing signal and the clock and circuit integration is made easy with digital constitution for the timing circuit to pick up the brust signal included in the video signal.
