WebThe discrete Fourier transform (DFT) is a method for converting a sequence of \(N\) complex numbers \( x_0,x_1,\ldots,x_{N-1}\) to a new sequence of \(N\) complex numbers, \[ X_k = \sum_{n=0}^{N-1} x_n e^{-2\pi i kn/N}, \] for \( 0 \le k \le N-1.\) The \(x_i\) are thought of as the values of a function, or signal, at equally spaced times \(t=0,1,\ldots,N-1.\) The … WebRoad traffic statistics.
