WebOur first attempt. Putting those ideas together, we arrive at the following sketch of a depth-first traversal algorithm for a graph. DFT (Graph g): let startVertex be any vertex in g DFTr (g, startVertex) DFTr (Graph g, Vertex v): visit (v) for each vertex w such that the edge v → w exists: DFTr (g, w) DFT is the complete algorithm; it's job ... 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 ...
