Properties of the z-Transform † The z-transform has a few very useful properties, and its def-inition extends to infinite signals/impulse responses. The range of variation of z for which z-transform converges is called region of convergence of z-transform. Properties of ROC of Z-Transforms ROC of z-transform is indicated with circle in z-plane.

Introduction to the z-transform Module for Chapter 9 z-transforms and applications Overview The z-transform is useful for the manipulation of discrete data sequences and has acquired a new significance in the formulation and analysis of discrete-time systems. It is used extensively today in the areas of applied mathematics, digital signal processing, control theory, population science, economics. These discrete models are solved with difference equations in a manner that is analogous to solving continuous models with differential equations. The role played by the z-transform in the solution of difference equations corresponds to that played by the Laplace transforms in the solution of differential equations. 9.1 The z-transform The function notation for sequences is used in the study and application of z-transforms. Consider a function defined for that is sampled at times, where is the sampling period (or rate). We can write the sample as a sequence using the notation.
