摘要： 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.

摘要： A tangential error signal generator to be used in a PAL type video disc player in which a synchronous signal such as a pilot burst signal extracted from a color video signal read from a video disc of PAL type is compared with a reference periodic signal so as to produce a phase error signal representative of the phase difference between the synchronous signal and the reference periodic signal. The phase error signal is amended in accordance with the jump direction and the jump distance required for a desired mode of reproduction in the video disc player such as a still, fast or slow mode of reproduction.
