Abstract

PURPOSE: To obtain the frequency converting carrier signal generator circuit for the color video signal recorder which features a simple constitution and high stability of the frequency.
CONSTITUTION: The luminance signals given from LPF14 are supplied to synchronous isolator 20, divider 21 and BPF22, and thus the frequency signal of 1/4fh (fh: horizontal frequency) is obtained from the output of BPF22. The low band conversion carrier chrominance signal given from LPF25 is supplied to burst gate circuit 26 which is gated by the output of 1/4fh given from BPF22, and part of the low band conversion burst signal gated at circuit 26 is supplied to sample holding circuit 27. The 1/4fh given from BPF22 is supplied also to sampling signal generator circuit 23, and the sampling signal of circuit 23 is supplied to sample holding circuit 27. Then variable frequency oscillator 28 is controlled by the output of circuit 27, and the output of oscillator 28 is supplied to frequency converter circuit 24 in the form of the low band conversion carrier signal.
