Hence, if any two ( − π / T s, π / T s) bandlimited continuous time signals sampled to the same signal, they would have the same continuous time Fourier transform and thus be identical. Thus, for each discrete time signal there is a unique ( − π / T s, π / T s) bandlimited continuous time signal ...
