چکیده
The Fast Fourier Transform, the FFT, is one of the most widely used algorithms in science and engineering. It is used both in signal processing and for the solution of partial differential equations. For instance, FFTs are used in so–called Fast Poisson solvers. It is also used in combination with cyclic reduction for the FACR (Fourier Analysis Cyclic Reduction) [4] method for Poisson’s equation. FFTs are also used for fast convolution. We will

The FFT performs butterfly computations on pairs of data elements that differ in a single bit. The computations start from the most significant bit in the index space and proceeds monotonically to the least significant bit. In a binary cube, adjacent nodes differ in a single bit in their addresses. Thus, mapping data to nodes by a binary encoding of the indices is suitable for the FFT. We assum...
متن کاملPathologies cardiac discrimination using the Fast Fourir Transform (FFT) The short time Fourier transforms (STFT) and the Wigner distribution (WD)
This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short time Fourier transform (STFT and the Wigner distribution (WD) in analysing the phonocardiogram signal (PCG) or heart cardiac sounds. The FFT (Fast Fourier Transform) can provide a basic understanding of the frequency contents of the heart sounds. The STFT is obtained by calculating the Fourier tran...
متن کاملFast Fourier Transforms for the Rook Monoid
We define the notion of the Fourier transform for the rook monoid (also called the symmetric inverse semigroup) and provide two efficient divideand-conquer algorithms (fast Fourier transforms, or FFTs) for computing it. This paper marks the first extension of group FFTs to non-group semigroups.

متن کاملData - sparse matrix computations Lecture 2 : FFT - The Fast Fourier Transform Lecturer : Anil Damle
It is without a doubt, one crucial piece of the toolbox of numerical methods. The FFT or Fast Fourier Transform is a fast algorithm used to compute the Discrete Fourier Transform. It is one of the most common discrete transforms used today. Note: While many other algorithms used throughout this course can be coded up for use in other projects, you shouldn’t attempt to do this with the FFT. The ...
