Applying digital filters to data

Description Digital filtering with LTPDA filters objects.
Examples How to filter a data series in LTPDA.


Digital filtering in LTPDA can be performed by a call to the ao/filter method. ao/filter method is a wrapper of the standard MATLAB filter method. Details of the core algorithm can be found in the proper documentation page.


Given an input analysis object (can be a time series or a frequency series object) a_in, digital filtering operation can be easily performed:

    a_out = filter(a_in,fobj)

Where fobj is a filter. It can be a MIIR, a MFIR or a FILTERBANK object.

The filter object fobj can be also embedded in a plist

    pl = plist('filter', fobj);
    a_out = filter(a_in,pl)
