Smoothing
The individual measured values are smoothed by digital filtering. The smoothing can be
adjusted in four steps, in which the smoothing factor k multiplied with cycle time of the
electronic module equals the time constant of the smoothing filter. The greater the
smoothing, the greater the time constant of the filter.
The following diagrams show the step response with the various smoothing factors in
relation to the number of module cycles.
