TH6378B - Rhythm signal generation system - Google Patents

Abstract

A television receiver consists of a fixed-front circuit (FLL)(226-232) which generates a resonant signal with a frequency of N times the linear frequency. and will have a fixed phase page Connect a horizontal sync signal. The resonant signal generated by this PLL has a frequency whose tendency to oscillate is between N+l and N+l times the line frequency. in order to compensate for the vibrations in resonant signal frequency A phase aligned circuit (236) is attached to the PLL to phase the resonant signal. It is aligned with the horizontal signal generated by the PLL. When each horizontal pulse occurs, the PLL may consist of an overtime device (234), which overtimes the drive signal. Horizontally fed to the PLL phase comparator, this timer shifts the phase of the horizontal signal and the linear resonant signal. compared to the horizontal signal effectively to compensate for the time wasted in the process Signal generation to generate horizontal drive signal and rhythm signal.
