Maybe more like a fourier transform.

I didn't see anything about fourier transforms in TFA? Do you have links?

something something Fourier transform.

Maybe this will help https://dsego.github.io/demystifying-fourier/

I wonder if anyone tried applying fourier/inverse fourier transform on it

The search keyword to learn about it is Fourier Transform: https://en.wikipedia.org/wiki/Fourier_transformAlong with the Wikipedia article and the obvious Internet search, there's a lot of good stuff that has been on HN: <a href="https://hn.algolia.com/?query=fourier%20transform&sort=byPopularity&prefix&page=0&dateRange=all&type=story" re

Sounds like a good subject of Fourier analysis.

you should talk/reference a bit more about the fourier transform aspect https://www.geogebra.org/m/t9uspumz
