7 Analog Filtering

If the measured signal is interrupted it is possible to eliminate the disruptions by

switching the lowpass filter on. It is possible to configure the filter for all inputs (it is not

possible to enable the filter for only one input). The filter parameter corresponds to the

filter time constant. Step response of the filter is shown in the graph below.
