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 ... WebMay 22, 2024 · Time Shifting. Time shifting shows that a shift in time is equivalent to a linear phase shift in frequency. Since the frequency content depends only on the shape of a signal, which is unchanged in a time shift, then only the phase spectrum will be altered. This property is proven below: Example 9.4. 2. We will begin by letting z [ n] = f [ n ...
