For the past couple of days, I was writing about a bit of a side project that I’m working on with my brother. It’s one of those things that as I’m doing this and writing, you know, code that does something interesting, that I still have what it takes to hack this stuff.

Maybe not business logic… but in the course of a few days I learned more about FIR filters, figured out a way of modeling them in Mathematica (and how they worked in the first place of course), wrote a C# program that does multi-octave decimation along with implementing the FIR filters, then be able to post-process the results in Mathematica.

You know what?

I still got it.
