WebFFT for Discontinuous Functions: Motivation For smooth periodic functions, the FFT provides a high accuracy. FFT results have greatly reduced accuracy for discontinuous … Web1-D discrete Fourier transforms #. The FFT y [k] of length N of the length- N sequence x [n] is defined as. x [ n] = 1 N ∑ k = 0 N − 1 e 2 π j k n N y [ k]. These transforms can be calculated by means of fft and ifft , respectively, as shown in the following example. y [ 0] = ∑ n = 0 N − 1 x [ n]. which corresponds to y [ 0].
