INVERSE z TRANSFORM AND MOMENT PROBLEM
Aldo Tagliani · Probability in the Engineering and Informational Sciences · 2000
Numerical inversion of a one-sided z transform, corresponding to causal positive sequence, is considered. The numerical inversion requires the availability of a finite number of the transform's derivatives. The approximate analytical form is obtained by resorting to the maximum entropy principle. Entropy and then L1-norm convergence are proved.
