Abstract
The video signal reproduction apparatus having two kinds of equalizing circuits to correct the level of a frequency-modulated luminance signal, that is, a first equalizing circuit which raises the level of the upper sideband range of the frequency-modulated luminance signal and a second equalizing circuit which raises the level of the lower sideband range of the frequency-modulated luminance signal, so that the part of the frequency-modulated luminance signal where a horizontal synchronizing signal is not modulated is processed by the first equalizing circuit, while the part of the frequency-modulated luminance signal where a horizontal synchronizing signal is modulated is processed by the second equalizing circuit.
