This filter method simulates an arithmetic mean value calculation over several measurements. The setting
for filter strength takes affect on the attenuation.
The applied method is not exactly a true mean value calculation from the mathematical point of
view; due to the limited RAM storage capacity of a microcontroller a similar method is employed.The
maximum allowable attenuation should experimentally be derived.
F03
In the case of arrival of different distance values the sensor-near measured values are preferred.
F04
In the case of arrival of different distance values the sensor-far measured values are preferred.
