Webthe DFT spectrum is periodic with period N (which is expected, since the DTFT spectrum is periodic as well, but with period 2π). Example: DFT of a rectangular pulse: x(n) = ˆ 1, 0 ≤n ≤(N −1), 0, otherwise. X(k) = NX−1 n=0 e−j2πkn N = Nδ(k) =⇒ the rectangular pulse is “interpreted” by the DFT as a spectral line at frequency ...
