I would like to thank both of you very much for the fast replies.
To overcome the problem of units redefinitions etc, I tried to use numerical integration algorithm: I simply wrote the definition of the fourier transform and I tried to compute numerically.
the obtained data are in perfect agreement between numerical and theoretical in both cases (exp(-t) and exp(-2t).
But, I would like to understand better what Charlie Roberts was saying about reading in the literature about the passage between dft and fourier transform, can you suggest a good source?
thank you very much again.
