In toggling MR17 (Sharpness Filter Enable/Disable) and setting
the Filter Gain register value to 99hex it can be seen that the line
contours of the cross hatch pattern change their sharpness
Adaptive Filter Control Application
The figure below shows a typical signal to be processed by the
Adaptive Filter Control block.
The following register settings where used to obtain the
results shown in the figure below, i.e., to remove the ringing
on the Y signal:
Input data was generated by an external signal source.

The figure below shows the output signal when changing the Adap-
tive Filter mode to Mode B (MR56 = “1”).
The Adaptive Filter control can also be demonstrated using the
internally generated crosshatch test pattern and toggling the Adap-
tive Filter Control bit (MR57) using the following register settings:
