2.2.2.1 Color Low-Pass Filter
Color low-pass filter frequency responses are shown in Figures 2–5 to 2–8. High filter bandwidth preserves sharp
color transitions and produces crisp color boundaries. However for nonstandard video sources that have
asymmetrical U and V side bands, it is desirable to limit the filter bandwidth to avoid UV crosstalk. Color low-pass
filter bandwidth is programmable by enabling one of the three notch filters.
