Dft periodicity property
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.
