filtfilt

A zero-phase digital filtering implementation in Python.
This repository is just to re-implement the scipy.signal.filtfilt() in pure Python.

Usage

If you only want to run the function filtfilt() without tests:

poetry install --no-dev

If you also want to run the tests:

poetry install

After installing all necessary dependencies, run:

pytest

Or read your own data, get b and a, and then pass into filtfilt().

Note

For simplification,

1. 1D array support only.
2. Padding method support only.
