This tutorial focused on general application of FFT for graphics processing units (GPUs) with C++ AMP FFT Library. The Fourier Transform, FFT & PSD. The Fast Fourier Transform (FFT) is an efficient algorithm to compute the discrete Fourier transform (DFT) and its inverse. FFT 2013: Phaseless Reconstruction. Ř Transient, intermittent behavior. Deal with expansion of functions in terms of a set of basic functions. Ř Suitable for time invariant signal. It breaks down a signal into sinusoids of different frequencies transforms from time domain to frequency domain. Ř Long-lived, stationary signals. Yesterday, I got back from the February Fourier Talks 2013 at the University of Maryland, and I wanted to share a bit of what I learned there. €�The FFT has been called the most important numerical algorithm of our lifetime. Ř Suitable for time-varying phenomena. This is a method to calculate the discrete Fourier transform and its inverse.
