Abstract

PURPOSE: The burst signal in the reproduced carrier chrominance signal and the prescribed output signal of the fixed oscillator are phase-detected to control the voltage-control-type oscillator, thereby making it possible to maintain the output chrominance carrier frequency at a constant value even if the input chrominance carrier frequency varies.
