Note:
Rotary SSI/Gurley devices with Turns Counting = False: filtering may be undesirable because
as the signal is filtered, the angle step that occurs every 360 degrees causes ringing due
to the high-frequency content of the step. Filtering occurs normally if the encoder is operated
in a range that does not include the angle step.

Debounce Filter: specifies the filtering applied to the input signal.
Debounce filtering is typically used to clean up the shape of the Encoder Properties
pulse in situations where there are long cable runs or signals with
long rise and fall times (for example, a proximity switch counting
gear teeth) with noise riding on the signal.
The default setting (40 ns) works for most applications. If the noise
results in extra counts, you may need a longer debounce time
setting. If the debounce setting is too long, the debounce filter will
filter out the encoder signal.
