Luminance filter select [1:0] selects one of the four chrominance trap (notch) filters to produce luminance

signal by removing the chrominance signal from the composite video signal. The stopband of the

chrominance trap filter is centered at the chrominance subcarrier frequency with stopband bandwidth

controlled by the two control bits. See the following table for the stopband bandwidths. The WCF bit is

controlled in the chrominance control #2 register, see Section 3.21.25.
