Understanding the FFT, Second Edition, Revised

Rating:
Summary: I've been looking for a book like this for 10 years
Review: This book contains all the necessary info to obtain a working knowledge of DFT and FFT. It contains many GWBASIC example programs so the reader can get a good grasp of what the algorithms are supposed to do. "C" progammers would have no difficulty rewitting these algorithms in "C".
Notes:
(1) most GWBASIC programs run without modification under QBASIC.
(2) the ones that don't run under QBASIC contain graphics statements and are easily fixed using QBASIC help.
(3) if you hate to enter source code, the software is available on diskette from the publisher for a small fee ...(includes GWBASIC and QBASIC examples)
(4) I've discovered "BASIC programmer" web sites where both GWBASIC and QBASIC are available for free download.
