WebThe basics of FFT algorithms involve a divide-and-conquer approach in which an N-point DFT is divided into successively smaller DFTs. Many FFT algorithms have been developed, such as radix-2, radix-4, and mixed radix; in-place and not-in-place; and decimation-in-time and decimation-in-frequency. In most FFT algorithms, restrictions may apply. WebThis calculator is an online sandbox for playing with Discrete Fourier Transform (DFT). It uses real DFT, the version of Discrete Fourier Transform, which uses real numbers to represent the input and output signals. DFT is part of Fourier analysis, a set of math techniques based on decomposing signals into sinusoids.

Therefore the IDFT scaling is a factor 100 less than it should be to match the forward transformation and your values are a factor of 100 too large. Since you're doing a 2-D DFT/IDFT, the factor 100 is missing twice, so your rescaling should be 100^2. rush trailer
