Order of butterworth filter in lsrepost

    • Shreyas Joglekar

      What is the default SSorder of butterworth filter in lsprepost? And is it possible to change it?

      I can choose frequency but cannot set the order. I can filter it externally (MATLAB/python etc.) with desired frequency and order. But prefer to do it in lsprepost if possible.

      The "BW” filter in LS-PrePost seems to filter data forward and backward with a second-order Butterworth scheme. You may want to confirm that by comparing the BW-filtered data to results from your external filter.
