Color Low-Pass Filter
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. The color low-pass filter bandwidth is programmable to enable one of the
three notch filters. Figure 3-4 and Figure 3-5 represent the frequency responses of the wideband color
low-pass filters.
