The Fourier transform does not converge for all sequences — the infinite sum may not always be finite. Similarly, the z-transform does not converge for all sequences or for all values of z.

The set of values of z for which the z-transform converges is called the region of convergence ROC. The zeros and poles completely specify X z to within a multiplicative constant. The z-transform has a region of convergence for any finite value of a. This is consistent with the fact that for these values of a the sequence an u[n] is exponentially growing, and the sum therefore does not converge.

Specifying the ROC is therefore critical when dealing with the z-transform. However, for discrete LTI systems simpler methods are often sufficient.
