Filter Settings

Using one of the following filter types, filters in the signal path can be activated in such a way
that vibration frequencies that excite the sensor are suppressed. These vibrations could be trig-
gered by a running engine or gearbox, for example. In this way, the quality of the angle output
can be adjusted despite disturbing vibrations. The filter type, the filter order and the width of a
low-pass filter can be set.

The filter setting needs a filter type, filter order and a cut-off frequency to operate as a low-pass
filter. This could be one of the following items:
Filter Types
Butterworth lowpass
Butterworth highpass
Bessel lowpass
Bessel highpass
Tschebyscheff lowpass
Tschebyscheff highpass
