Sorry for the delay, took a while to find how our company library
searcher works 8->.

-Theory and Application of Digital Signal Processing, Rabiner, Gold,
 Prentice Hall  ISBN 0-3-914101-4, The BIBLE, a must

-FFT, Brigham E. Oran , German Edition ISBN 3-486-25861-3 
 a very good book about all details of the fourier transform, examples,
 graphs, everything you need

These are texts for engineers, knowledge of usefull standard mathematics like
complex numbers, complex exponential-function, integration and differentiation
are neccessary to understand.
