IIR filter

The filter with IIR characteristics is a discrete time, linear, time invariant filter that can be set to eight levels

(level 1 = weak recursive filter, up to level 8 = strong recursive filter)

The IIR can be understood to be a moving average value calculation after a low-pass filter.

Through the synchronization mode FreeRun the IIR filter operates with an internal cycle time of 180µs (1 or

2 channels) or 500µs (4 channels).
