WebFeb 23, 2013 · 1. If you take the absolute value of the fft, you destroy the phase information needed to reconstruct the original signal, i.e. the moment you compute. X = abs (fft (x,N)); You cannot go back via ifft, because now you only have the magnitude. Also, the inverse transformation only works if you use the same number of FFT bins with NFFT>=length (x).

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:
