AUTOMATIC FINE TIME-CORRECTING CIRCUIT FOR TIME CORRECTING THE OUTPUT OF A COARSE TIME CORRECTOR IN A COLOR TV SYSTEM

摘要

An automatic fine time-correcting circuit coupled to the output of the coarse time corrector in which the reference signal used in the phase comparator circuit is taken off a color carrier regenerator circuit, and the output of the fine time corrector is fed back to the coarse corrector circuit through a threshold device including a pair of antiparallel connected diodes.
