2.2.2.1Color 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 2−4 and Figure 2−5 represent the frequency responses of the wideband color low-pass filters.
