ED/HD SHARPNESS FILTER AND ADAPTIVE FILTER
APPLICATION EXAMPLES
Sharpness Filter Application
The ED/HD sharpness filter can be used to enhance or
attenuate the Y video output signal. The register settings in
Table 47 were used to achieve the results shown in Figure 73.
Input data was generated by an external signal source.

Adaptive Filter Control Application
The register settings in Table 48 are used to obtain the results
shown in Figure 75, that is, to remove the ringing on the input
Y signal, as shown in Figure 74. Input data is generated by an
external signal source.
