Command line FFT
A simple command line utility to produce an FFT/IFFT of ASCII data
Ever had a bunch of ASCII data that you would like to have a quick look at in frequency domain, but don't want to fire up some bulky analysis software package just for that? Well, I have... So I wrote this tiny tool. It is based on fftw (www.fftw.org) and boost's program options (boost.org). cli-fft is really simple: All it does is to receive ASCII data from a file or standard in, FFT it and write out the result into a file or to standard out. -

MAT-MECAS
Cell impedance analysis software.
MAT-MECAS is used for calculation of impedance parameters of a cell from recorded current responses elicited by bipolar voltage stimuli in a whole-cell patch-clamp experiment. The calculations are based on a FFT deconvolution procedure and on approximation of the reconstructed currents with a theoretical function. The impulse response of the signal path is necessary for the calculations. Read manual first! For testing MAT-MECAS we provide a sample data along with sample stimulation protocols. -

bel_fft
FFT co-processor in Verilog based on the KISS FFT
bel_fft is a FFT co-processor that can calculate FFTs with arbitrary radix. It is a hardware implementation of the free software Kiss FFT ("Keep it simple, Stupid!"). The target was to allow a simple replacement of the software code with the hardware implementation. Therefore bel_fft comes with a software driver that is compatible with the Kiss FFT routines. bel_fft also has a modular architecture and allows interfacing different bus architectures. -

MSU's Sparse Fourier Repository
The Home of DMSFT, AAFFT, GFFT, and MSFFT.
...Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.) AAFFT, implemented by Mark Iwen in 2008. This code is easy to use, and documented well, but not implemented very efficiently. It is much slower than it should be. 3.) GFFT, implemented by Ben Segal and Mark Iwen. This code is less easy to use, and also not terribly efficient. ... -

A More Accurate Fourier Transform
Computes Accurate Fourier Transform via Explicit Integration not FFT
Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented in reasonable times with modern computing power. ... -
