Filters

Filters for the Digital Linear Filter (DLF) method for the Hankel [Ghos70]) and the Fourier ([Ande75]) transforms.

Starting with v2.3.0, the actual filters are not stored here any longer, but are loaded from libdlf (emsig/libdlf). Each filter is documented in its own docstring, also indicating the license under which it is distributed.

The filter wer_201_2018 was designed with the add-on fdesign, see emsig/article-fdesign.

Classes
