I believe you spelled "open source POSs" incorrectly. Also if you want an FIR filter go here and press the button. It provides the source code for you, too. This may be the most trivial algorithm in all of signal processing, which is why it's so frustrating to see somebody completely whiff on it and a bunch of HN amateurs upvote and defend it.

I believe that you know a lot about signal processing, but please don't express it in a snarky, dismissive way. If you can't post civilly and substantively, please don't post at all.
