WebC. A. Bouman: Digital Image Processing - January 9, 2024 3 Continuous Time Delta Function • The “function” δ(t) is actually not a function. 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 ...

Web2 Answers. Sorted by: 8. The difference is pretty quickly explained: the CTFT is for continuous-time signals, i.e., for functions x(t) with a continuous variable t ∈ R, whereas the DTFT is for discrete-time signals, i.e., for sequences x[n] with n ∈ Z.
