FOSS Filter design suite with KiCAD/LTspice schematics as output

[Detzi]

Good Day,
in the past weeks i worked on a tool that creates active and passive electronic filters based on the inputs a user makes. You can choose from a wide variety of pole calculations as well as a few different architectures. The Program looks like this:



For the output format you can select for example a Eeschema format which has everything preset to be evaluated with its current NGspice. Of course you can also decide to create a simulation file for LTspice or just output plain text.

The GitLab repo is located here https://gitlab.com/IBDetzler/ibdfc and you can find pre-build versions of the program for Linux and Windows based systems on my Website https://www.ing-detzler.de/ibdfc.html . I tested the builds to run under Windows 10, Fedora 31, Ubuntu 18.04 and 19 but they should run on almost any distro.

I hope my program can be of good use to someone, i have applied a GPLv3 License to it so it should be easy to integrate in other Projects. Let me know of your thoughts and maybe we can work together on a future version :slight_smile:
