View Full Version : Band Pass Filtering / Discrete Fourier Tansform

So, I'm trying to learn how to do a discrete fourier transform, with an emphasis on band-pass filtering (for a simple audio wave)

Can anyone suggest online resources for this? My boss let me borrow his Bracewell to study the subject but I'm already lost on convolution. I'm still an undergrad (physics) and I'm starting to think I might never be able to learn this without some graduate classes.

I'm using matlab, but for now, just understanding how to build and understand the algorithms involved would be nice, considering that I'm transforming real world data and not a simple function.
