The FFT is nothing but an effective way of computing the discrete
Fourier transform (DFT) of a finite length signal. Any introductionary
text on digital signal processing explains these things without being
too mathematical about it (although you need to know your basic linear
algebra and analysis). I like the following book:
J. G. Proakis & D. G. Manolakis,
"Digital Signal Processing, - Principles, Algorithms, and Applications"
Here's a link as well:
