Stability reserve of designed filter not sufficient.

Description

It is not possible to design a stable filter for all filter parameters, e.g. due to the limited calculation accuracy. Possible solutions are:

  • Reduce order P-AXIS-00140 of the filter
  • Reduce the reciprocal bandwidth P-AXIS-00080 of band-pass or band-stop filters
  • Choose a different filter prototype P-AXIS-00153
  • Increase the ratio of cut-off frequency to sample rate
