Base band compensation for an IF stage in a television provides
significant advantages over compensation applied to the composite signal.
Each base band color difference signal is filtered to obtain cross-talk
elements, which are then applied to the opposite channel to eliminate the
cross-talk components from the color difference signal channels. The
compensation technique is applicable to IF stages generally, including
those based on SAW filters. High and low gain compensation of the
cross-talk compensated signals may also be performed to reduce distortion
in the compensated signals. The base band compensation tends to reduce or
eliminate visual artifacts in a television image, especially where sharp
contrast transitions occur in the image.
