Abstract
A selective intermodulation correction system which can correct for in-band intermodulation products which are formed in a high end of a video sideband region generated in the common amplification of a television signal. The selective intermodulation correction system operates to generate an intermodulation product which is equal in amplitude but opposite in phase to in-band intermodulation products formed at the high end of the video sideband region. By combining such a signal to a conventionally corrected television signal, the in-band intermodulation products formed in the high end of the video sideband region can be cancelled.
