  Discrete Fourier Transform (DFT) - MATLAB & Simulink
  
  Introduction Spectral analysis is the process of identifying component frequencies in data. For discrete data, the computational basis of spectral analysis is the discrete Fourier transform (DFT). The DFT transforms time- or space-based data into frequenc

245C, Notes 2: The Fourier transform | What's new

日期：2024-07-23

There’s a strong superficial similarity between the Fourier transform and its inverse and similar inverse pairs in combinatorics, e.g. the binomial transforms, the Stirling transforms, and Mobius inversion. If the Fourier transform is essentially group-th...

日期：2024-07-29

Fourier transforms of data with sizes that are not factorable into small prime factors can be very slow – and many programs only implement FFT of arrays with dimensions that are powers of two. In Gwyddion, however, the Fourier transform can be applied to ...
