This topic is discussed in the "Numerical Recipes ... The Art of
Scientific Computing" books by Press, Flannery, Teukolsky and
Vetterling.  I have a copy of "Numerical Recipes in C" (ISBN
0-521-35465-x).  Chapter 12 is titled Fourier Transform Spectral
Methods with section 12.2 containing a good explanation of the FFT.

For a less mathematical discussion, I remember Scientific American had
an article on the Fourier Transform a few years ago (1988, 89?).

I believe you can get working FFT code from netlib.  To get an index,
send an email message containing only "send index" to netlib at ornl.gov.
