ABSTRACT:
To improve TV image reproduction, and to suppress interference in the luminance channel of a color TV decoder, a controlled portion of the amplitude of a part of a TV signal, which part is within the frequency range of the chroma subcarrier, is subtracted from the TV signal. The portion of the luminance signal which is within the frequency range of the chroma subcarrier is rectified to derive a control signal and the amplitude of the controlled portion which is subtracted is controlled as a function of the controlled signal. Non-linearities of reproduction by the TV tube and of human perception can be compensated within the circuit which includes, for example, a matrix, and a non-linear signal transfer channel, or derived from the TV tube itself.
