I'm battling my way learning about and gradually getting a grasp of Fourier analysis.

This project is potentially helpful:

Unfortunately most of the commenting is in German, so although I can see how to use the code, I can't really figure out what it's doing.

Is there an English-language assembler example on this site that I'm missing?

Cheers,

Joey

Hallo, last year I've tried the same thing and results are here (www is in CZ language, but code is ENG commented):

MCU code:

It's a bit different from Chans implementation - I'm using DIT instead of DIF decimation.

Thanks Smaslan; Google has done what appears to be a remarkably good job of translating you web page!

I've downloaded your code and will be doing some hard thinking over the next couple of weeks.

Cheers,

Joey

Does your browser produce translated lines of text extending 6 feet off screen as if there were no carriage returns? Real difficult to read with all the scrolling.

Nope; using Chrome here.
