WebDec 4, 2024 · DTFT. DFT. DTFT is an infinite continuous sequence where the time signal (x (n)) is a discrete signal. DFT is a finite non-continuous discrete sequence. DFT, too, is calculated using a discrete-time signal. DTFT is periodic. DFT has no periodicity. The DTFT is calculated over an infinite summation; this indicates that it is a continuous signal. Web1.
