Abstract: An equalization apparatus in which a variable equalizer is used to equalize the frequency response of an FM video signal obtained by frequency-modulating a carrier signal with a video signal in which a reference signal of a constant frequency is inserted during a predetermined interval. The equalization apparatus includes a comparator section for making a comparison in amplitude between first upper and lower sidebands in the FM video signal and a control section for controlling the variable equalizer in accordance with an output of the comparator section.
