Luminance filter select[1:0] selects one of the four chroma trap filters to produce a luminance signal by removing the
chrominance signal from the composite video signal. The stop band of the chroma trap filter is centered at the chroma
subcarrier frequency with stopband bandwidth controlled by the two control bits. Refer to Figure 2–12, 2-13 and 2-14
for the frequency responses of the filters. The control 00 is the default mode.
