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. That's why the CTFT is defined by an integral and the DTFT is defined by a sum: tabela fox 2012
