Fft fast fourier
WebThe Fast Fourier Transform (FFT) is an efficient algorithm to calculate the DFT of a sequence. It is described first in Cooley and Tukey’s classic paper in 1965, but the idea actually can be traced back to Gauss’s unpublished … WebThe FFT is one of the truly great computational developments of this [20th] century. It has changed the face of science and engineering so much that it is not an exaggeration to say that life as we know it would be very different without the FFT. -Charles van Loan 3 Fast Fourier Transform:n BriefsHistory Gauss (1805, 1866).
