WebFourier Transform Properties. Steven W. Smith, in Digital Signal Processing: A Practical Guide for Engineers and Scientists, 2003 The Discrete Time Fourier Transform. The discrete time Fourier transform (DTFT) is the member of the Fourier transform family that operates on aperiodic, discrete signals. The best way to understand the DTFT is how it … WebThis is the DTFT, the Fourier transform that relates an aperiodic, discrete signal, with a periodic, continuous frequency spectrum. The mathematics of the DTFT can be understood by starting with the synthesis and analysis equations for the DFT (Eqs. 8-2, 8-3 and 8-4), and taking N to infinity: botas ixon
