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 settings can be defined in the "Filter settings" parameters,
as listed in the "Parameter table" chapter.
