The following figure shows how this works using a 60 Hz interference frequency suppression
as an example. A 60 Hz interference frequency suppression corresponds to an integration
time of 16.6 ms. The analog on-board I/O supplies a measured value to the CPU every 1.04
milliseconds within the integration time.
