WebAug 12, 2016 · When we perform the DFT on real-world finite-length time sequences, DFT leakage is an unavoidable phenomenon. Let us construct an example to observe this in detail. Example. Assume a signal with frequency 4 4 kHz at a sample rate of F S = 16 F S = 16 kHz. s[n] = sin2π 4 16 n s [ n] = sin 2 π 4 16 n. WebThere's an important property of the DFT known as the shifting theorem. It states that a shift in time of a periodic x(n) input sequence manifests itself as a constant phase shift in the angles associated with the …
