I like to learn FFT processing in abc way...can anyone point me good
book or student course booklet.
"Understanding Digital Signal Processing" by Richard Lyons.

Chapter 1 is abc, but thereafter, at least for me, the math became
progressively harder and my comprehension diminshed accordingly.
Using the examples and after much study, I understood the mechanics
of the math to write a Discrete Fourier Transform (DFT) and low-pass
filter, however, I did not understand the beauty of the math (if you
get my meaning) to go past the first half of the book.
The DSP newsgroup is comp.dsp .
Here's Java source code using FFT from Craig Lindley's book of
"Digital Audio With Java":
