Abstract
PURPOSE: To cut the high frequency portion of a chrominance signal by a simple constitution to make possible correction for reinforcement by selecting the resonance frequency of resonance circuit connected to a video detection circuit higher than the frequency of chrominance signal and lower than the frequency of sound carrier.
CONSTITUTION: Coil 12 and capacitor 13 are connected between the output of video detection circuit 4 and earth and constitute a series resonance circuit. Load 11 is connected between the connection point between coil 12 and capacitor 13 and the earth. In this case, the resonance frequency of coil 12 and capacitor 13 is selected higher than chrominance signal frequency fc and lower than sound carrier frequency fs. Thus, low frequency video signal components pass through coil 12 without attenuation and are supplied to load 11; around resonance frequency, both terminals of coil 12 are corrected for reinforcement. Namely, it is possible to cut the high frequency of chrominance signals and correct them for reinforcement by a simple constitution.
