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 46 were used to achieve the results shown in Figure 75.
Input data was generated by an external signal source.

See Figure 75.
Adaptive Filter Control Application
The register settings in Table 47 are used to obtain the results
shown in Figure 77, that is, to remove the ringing on the input
Y signal, as shown in Figure 76. Input data is generated by an
external signal source.
