Abstract
An apparatus for suppressing noises in a color video signal is constructed to extract a frequency band component of the color video signal, to limit the amplitude of the extracted frequency band component, and to subtract the component, which is limited in amplitude, from the color video signal. Thus, a beat component such as a beat component generated by the interference between the main carrier signal and the color carrier signal of a recording video signal is removed from a video signal obtained after demodulation.
