If we want to approximate the CTFT using rectangular integration, we need to multiply the DTFT sum by Ts for the DTFT to approximate the CTFT. Because the DFT samples are samples of the DTFT, the DFT samples need to be muliplied by Ts as well.

WebAnswer (1 of 3): First, the DTFT is applied to discrete signals only. There is not a DTFT of a continuous signal. Then, if you sample the continuous signal f(t) to get a discrete f[n]=f(nT), and you get the DTFT of f[n] which is a discrete signal — so it now has a defined DTFT, — you still have ...

WebJan 25, 2024 · Therefore, the Fourier transform of a discretetime sequence is called the discrete-time Fourier transform (DTFT).
