Support non-standard filters #3

Closed warrenwoolseyiii closed 9 months ago

warrenwoolseyiii commented 9 months ago

The firwin2 FIR filter generator can support weird and non standard filters. There should be a filter mode that accepts a frequency range or isolated list of frequencies and desired gains to filter which is what the firwin2 function specializes in.

Initial support now added as of: https://github.com/warrenwoolseyiii/common-embedded-filters/commit/c285cb4e8f3f82a700c8ebbf38a3d20afa464d3c

I still have to support custom gain settings coupled with frequency ranges.
