Abstract
Luminance/chrominance separating apparatus in which a luminance signal and chrominance signal are extracted from a composite color television signal by a comb filter. A low frequency signal component is extracted from the chrominance signal and passed through a variable attenuator. The low frequency signal component from the variable attenuator is added to the luminance signal to produce a compensated luminance signal.
