WebThe discrete-time Fourier transform of a discrete sequence of real or complex numbers x[n], for all integers n, is a Trigonometric series, which produces a periodic function of a frequency variable. When the frequency variable, ω, has normalized units of radians/sample, the periodicity is 2π, and the DTFT series is: [1] : p.147.

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.
