I wanted to understand DFT and FFT in detail. I bought several books. After reading ten pages of Understanding the FFT, Second Edition, I bought Mr. Zonst's follow-on book on FFT Applications. Mr. Zonst has a unique way of presenting to the reader the exact information at the exact level of detail that people interested in DFT and FFT need. I have read his first book once and am reading it again because I don't want to miss a single detail. He must be a mind reader, because he answers my questions. I thought I was the only one who didn't know if the time domain input to the DFT could be real numbers or did it have to be a complex number array. As if he read my mind he answered my specific question. He did mention we could buy the BASIC code listings but I don't know how to purchase them. This book is a ten star book on FFT and DFT. If Anders E. Zonst writes another book on DFT, FFT I want one! He is the best teacher I have known. Thank you Mr. Zonst for helping those of us that never had DSP in engineering school because there were no digital signals at that time. Jim Laycock

I bought this book to gain a practical understanding of Fourier Transforms and how to implement them with real data. I already had a conceptual understanding of FTs but not a practical one to where I could use them. This book bridged that gap for me and it seems as though that was among the author's intentions were when he wrote it. I would recommend this book and its companion to anyone in the same position.

I needed to learn some basics about the DFT and FFT. "Understanding the FFT" seemed to be loaded with computer programs. I found very little to help me learn the concepts. "Who Is Fourier? A Mathematical Adventure" by the Transnational College of Lex and "Introduction to Fourier Analysis" by Norman Morrison where the books that helped me the most.
