I own both the Understanding the FFT volume and its companion, Understanding FFT Applications. They have their place on my technical bookshelf. If you are new to the FFT, or just so-so with undergrad level engineering math, then this series of volumes on the FFT is likely to prove a gold mine/5(4).
This book aims to introduce students and working engineers to Fourier analysis as it is practiced in industry (i.e., in the form of the DFT and FFT).
It avoids calculus so far as possible in an attempt to provide a solid foundation to the : $ Understanding FFT Applications Anders E.

Richard Lyons has thoroughly updated and expanded his best-selling second edition, building on the exceptionally readable coverage that has made it a favorite of both professionals and students : Paper. Book Abstract: "This useful, logical, unbiased, FFT compendium allows the user to quickly and accurately obtain practical information to implement a solution or simply acquire a general overview without spending months gathering this information elsewhere." —Jay Perry, Executive Vice President, Technology, Catalina Research, Inc.
"This is a practical guide for understanding and using FFTs. Real World FFT and Spectrogram Examples Vibration Analysis of a Car Engine. In real world applications there will typically be many different frequency components of a vibration profile as well as mechanical and electrical noise.
Let’s look at some data taken on a passenger car engine while it was idling and do some vibration analysis. Fast Fourier Transform - Algorithms and Applications presents an introduction to the principles of the fast Fourier transform (FFT). It covers FFTs, frequency domain filtering, and applications to video and audio signal processing.
As fields like communications, speech and image processing, and related areas are rapidly developing, the FFT as one of the essential parts in digital signal Reviews: 1.
$\begingroup$ @jjepsuomi, They key concept is that the DFT comes from a FT of the source signal convolved with a window of a train of Dirac Delta impulses. This is the approach taken by most textbooks and I am not a fan of this approach so I can't really make any recommendations.
If you are looking for a "meaning' of the DFT, I recommend you read my second blog article "DFT Graphical. The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used.
Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both. Topics include: The Fourier transform as a tool for solving physical problems. This book is a sequel to The Fast Fourier Transform.
The focus of the original volume was on the Fourier transform, the discrete Fourier trans form, and the FFT. Only a cursory examination of FFT applications was presented. This text extends the original volume with the incorporation of extensive developments of fundamental FFT Size: 8MB.

The Fourier transform is a particularly important tool of the field of digital communications. It allows us to study a signal no longer in the time domain, but in the frequency domain. The Author: Meinard Müller.
In your case it's easiest to simply ignore the outputs N/2 to N. You don't need them, they are just an artifact on how you calculate your FFT. The frequency to fft-bin equation is (bin_id * freq/2) / (N/2) where freq is your sample-frequency (aka 32 Hz, and N is the size of your FFT). In.
At the risk of sounding a bit too 20th Century, go find a copy of the book The Fast Fourier Transform and its Applications by E. Brigham. I have yet to find a better explanation and after reading it, all will become clear.
It's a bit pricey to buy, so your local library may be a better place to start. Theory and Applications of Computational Chemistry: The First Forty Years is a collection of articles on the emergence of computational chemistry.
It shows the enormous breadth of theoretical and computational chemistry today and establishes how theory and computation have become increasingly linked as methodologies and technologies have advanced.
It is hoped that this book will provide the background, references, programs and incentive to encourage further research and results in this area as well as provide tools for practical applications. Studying the FFT is not only valuable in understanding a powerful tool, it is also a prototype or example of how algorithms can be made efficient.
FFT Software. For those of us in signal processing research, the built-in fft function in Matlab (or Octave) is what we use almost all the time. It is adaptive in that it will choose the best algorithm available for the desired transform size.
For C or C++ applications, there are several highly optimized FFT variants in the FFTW package (``Fastest Fourier Transform in the West'') .
In a single useful volume, Vibration Fundamentals explains the basic theory, applications, and benefits of vibration analysis, which is the dominant predictive maintenance technique used with maintenance management programs.

Great post examining some of the reasons why the [FFT algorithm] is so fast compared to a naive implementation: > The goal of this post is to dive into the Cooley-Tukey FFT algorithm, explaining the symmetries that lead to it, and to show some straightforward Python implementations putting the theory into practice.The fft() function calculates the one-dimensional FFT of its input argument.
If the input argument is a vector, then the operation is pretty simple to understand; the output is just the result of efficiently calculating a discrete Fourier transform on the input.The book begins with a complete explanation of the often misunderstood topic of periodic sampling. The introduction to the important discrete Fourier transform, and its fast Fourier transform (FFT) implementation, is the most lucid and illuminating explanation available anywhere.
