Color Low-Pass Filter
In some applications, it is desirable to limit the U/V bandwidth to avoid crosstalk. This is especially true in case
of nonstandard video signals that have asymmetrical U/V sidebands. In this case, notch filters are provided
that limit the bandwidth of the U/V signals.
Notch filters are needed when the comb filtering turns off, due to extreme color transitions in the input image.
The response of these notch filters is shown in Figure 35. The notch filters have three options that allow three
different frequency responses based on the color frequency characteristics of the input video.
