Luminance Processing
The digitized composite video signal from the output of A/D converters passes through a luminance comb
filter or a chroma trap filter that removes the chrominance signal from the composite signal to generate
luminance signal. The luminance signal is then fed to the input of luminance signal peaking and coring
circuits. Figure 2–5 illustrates the basic functions of the luminance data path. In the case of S-video, the
luminance signal will bypass the comb filter or notch filter and be fed to the peaking and coring circuits
directly. High frequency components of the luminance signal are enhanced further by the peaking filter (edge
