Signal Conditioning

The selected A and B signals are conditioned before being applied to the quadrature decoder.

Each signal is sampled at a frequency of 50 MHz and flows through a digital filter.

With such a filter:

The following table shows for each possible value of the respective LineTrigFilter parameter:
