Study On Inverse -transform

Abstract

To know the relationship between the -transform, Fourier transform
and Laplace transform we need to know how to move from the -domain to
the discrete time sequence in other words we need the inverse -transform.
In this paper we study methods for finding the inverse of the -
transform as well as some important properties and examples of them. This
paper illustrates the relation between -transform and Laplace transform and
between -transform and Fourier transform Moreover we deduced the most
important correspondence between the -plane and - plane.
