Links to other interesting sites on the DFT:

One may find on the internet many pages that are dedicated to the DFT. Here is a small selection of links to such pages:

• Discrete Fourier transform (DFT) by Wolfram MathWorld
• Fast Fourier transform (FFT) by Wolfram MathWorld
• Discrete Fourier transform (DFT) by MathWorks
• Fast Fourier transform (FFT) by MathWorks
• Fast Fourier transform (FFT) FAQ by dspGuru
• FFTW A free C subroutine library for computing the DFT in one or more dimensions

There also exist on the internet several on-line DFT calculators or DFT applets, such as:

• A Java applet by the Stanford Exploration Project (SEP)
• A Java applet by eecircle
• DFT calculation using Wolfram Alpha

Note, however, that these sites may be based on different DFT definitions and conventions. Using them may therefore yield different results, as widely explained in the present DFT book (see, in particular, Chapters 2 and 4).

Note also that the above sites have not been checked here for their correctness, their ease of use, or any other criteria; they are only provided here for general information, without any guarantees or recommendations.
