Fourier Analysis

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,...

STIMATH is a high-level tool for mathematics, linear algebra, plotting and expression evaluation that can be used from any programming environment or even from a command line interface. It is an executable that takes a single argument, the name of a text file containing a series of MATLAB style...

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...

Fourier analysis often generates a spectrum with a pattern. Periodic evens can generate a central frequency with some sidebands due to modulation. This tools adds a number of cursors that can be dragged (using the mouse) or can be set to a specific x-locaiton (frequency) by keying in a number in...

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that:- The frequencies of the harmonic components are unevenly spaced-...
