Color Low-Pass Filter
High filter bandwidth preserves sharp color transitions and produces crisp color boundaries. However, for
video sources that have asymmetrical U and V side bands, it is desirable to limit the filter bandwidth to
avoid UV crosstalk. The color low-pass filter bandwidth is programmable to enable one of the three notch
filters. Figure 2-4 and Figure 2-5 represent the frequency responses of the wideband color low-pass filters.
