I think you'd be better off just getting a book on the FFT to start 
with.  Implementing it in Mathematica is trivial - indeed the built in 
functions Fourier[] and InverseFourier[], and the FourierTransform 
package probably do what you want.

A good introduction to the FFT and what it can do is:
	"The FFT, Fundamentals and Concepts" by Robert W. Ramirez,
	Prentice Hall, Inc, ISBN 0-13-314386-4

Hope this helps,
