Abstract
PURPOSE: To prevent a beat component from being generated by applying a frequency converter with a fundamental wave component and higher-harmonic component obtained by passing a low-band-converted reproduced chrominance signal through a non-linear circuit, and then by obtaining an original chrominance signal by obtaining a fruquency component of the sum.
CONSTITUTION: A color TV signal inputted to input terminal 1 is applied to band- pass filter 3, whose output is passed through inverse-bell filter 19 and then waveform-shaped by limiter 20 before being divided by quad divider 17. The output of this divider 17 is inputted to recording equalizer 21 with LPF characteristics, the output of which is applied to recording amplifier 8 as a signal having the same amplitude characteristics as filter 3 and divided by four. In reproduction mode, amplitude characteristics are flattened by reproducing equalizer 22 with opposite characteristics to the recording of a color signal separated from a luminance signal by LPF12 and through a limiter 23 as a non-linear circuit, a fundamemtal wave component and higher-harmonic component are applied to frequency converter 26, thereby outputting a color signal of the sum frequency of the fundamemtal-wave and higher-harmonic component from band-pass filter 27.
