IMAGE SIGNAL EQUALIZING CIRCUIT

摘要

A video signal equalizer circuit which can vary a gain of a frequency band of a video signal by an equalizer having a predetermined resonant frequency for a band width is disclosed. The circuit includes a plurality of active filter means(11-7) for developing resonant frequencies for each band width; gain control means(20) including a plurality of variable resistors(RL1-RL7), each of which is connected with each of the plurality of active filter means, the plurality of variable resistors for controlling a gain of an inputted video signal based on each of the resonant frequencies for band widths; and comparing means for comparing video signals from the gain control means and for amplifying the video signals at a predetermined rate.
