Finding the Fourier transform of a rectangular pulse..filtering the spectrum and regenerating the signal usingthe filtered spectrum is done...at the end Rayleigh theorem is proved by showing that the energy content of both time domain and frequency domain signals are equal..your comments are... Platforms: Matlab

From GUI can import arbitrary data or audio signal. Next we can plot them both in time and frequency domain. Also we can visualize the short time Fourier transform of that signal. Platforms: Matlab

I started with Adam Wyatt's FROG program (on this website) but added to it and edited it beyond recognition. I did, however, subtract one useful feature: This program, as written, is SHG-FROG and GRENOUILLE only!! (Adam Wyatt's program was more general.)--> The program "prepFROG" takes a raw...

Sculptor is a phase-vocoder-based package with real-time capabilites. You can use it to fiddle with soundfiles in the frequency domain, changing pitch and duration independently. Platforms: *nix

The Analysis & Reconstruction Sound Engine also known as ARSE, is a program that analyses a sound file into a spectrogram and is able to synthetise this spectrogram, or any other user-created image, back into a sound. The ARSE consists in two main parts, a spectrographer with a base-2... Platforms: *nix

ViPEC is a powerful tool for the analysis of high frequency, linear electrical networks. It takes a schematic description of the electrical network and performs a linear analysis in the frequency domain. The output is in the form of port parameters (S, Y or Z) with results presented on a user... Platforms: *nix

A Simulink model that generates and displays a simple cosine wave. The model computes the cosine function using the continuous phase method, which is based on Euler's formula for the complex exponential. The cosine generator is provided as a subsystem, which the user can copy-and-paste into other... Platforms: Matlab

This submission was created by Valery Tchkalov and Steve Miller to help engineers understand parameterization of hydraulic valves. The included white paper, simulation models, and MATLAB scripts cover the structure of a valve model, examples of how to use optimization algorithms to tune your... Platforms: Matlab

GFourier can help you use Fourier Analysis for image restoration. GFourier calculates the Fourier Transform of a given image and allows the use of filters in the frequency domain. The Inverse Fourier Transform is then used to substitute original image.. Get GFourier at SourceForge.net. Fast,... Platforms: *nix
