About the region of convergence of the z-transform

In general a sequence can be two-sided in that case the ROCof its z-transform is obviously the intersection of the ROC’s corresponding to its causal and anticausal parts We can summarize the results for the ROC of z-transforms as follows: The Region of Convergence of the z-transform of a sequence can have one of the following forms:

Does the ROC of the Z-transform of any signal contain poles?

The ROC of z-transform of any signal cannot contain poles. Explanation: Since the value of z-transform tends to infinity, the ROC of the z-transform does not contain poles.

What is the ROC of a Z-transform?

The ROC for a given , is defined as the range of for which the z-transform converges. Since the z-transform is a power series, it converges when is absolutely summable. Stated differently, must be satisfied for convergence. The Region of Convergence has a number of properties that are dependent on the characteristics of the signal, .

What is the region of convergence of the Z-transforms(Z)?

for which the in?nite sum converges, such set of values of z is called the Region of Convergence of the z-transformS(z). This document describes the possible shapes the Region of Convergence (ROC) may take. We start by describing the ROC shape of one sided sequences from which we’ll deduce the ROC shape for two sided sequences.
