Web3 Answers. Even & odd refer to the symmetry around n = 0. Even means x [ n] = x [ − n]; you can get the part for n < 0 by simply mirroring the part for n > 0 at the n = 0 line. Odd means x [ n] = − x [ − n]; you can get the part for n < 0 by simply mirroring the part for n > 0 at the n = 0 line and multiplying it by − 1. 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 … how are in russian https://norcalz.net
