Now, what this means in particular, I have to give you a little caution on this, is that there’s sort of one more general topic on this fast Fourier transform that I would ordinarily talk about and that is convolution, circular convolution, so I’m not going to do that. I will leave that up to you to read. There’s not much. There wouldn’t be much to do other than talk about the formulas and basic applications. The applications we’ll do in the context of linear systems coming up, so you’ll see some of that later. ...
