Discrete Fourier Transform (DFT)

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It is described first in Cooley and Tukey’s classic paper in 1965, but the idea actually can be traced back to Gauss’s unpublished work in 1805. It is a divide and conquer algorithm that recursively breaks the DFT into smaller DFTs to bring down ... iowa dot inspectors https://cleanbeautyhouse.com

Web1 Answer. Sorted by: 1. If you use the DFT formula, you get: Y [ k] = ∑ n = 0 2 N − 1 y [ n] e − 2 π k n 2 N. Now, substituting the definition of y [ n] you get: Y [ k] = ∑ n = 0 N − 1 x [ n] e − 2 π k ( 2 n) 2 N = ∑ n = 0 N − 1 x [ n] e − 2 π k n N. So, for 0 ≤ k < N you get that.
