![]() ![]() Now let us study the following typical examples. Next, we will briefly study two-sided z-transform for the noncausal sequence. Note that we deal with the unilateral z-transform first, and hence when performing an inverse z-transform (which we shall study later), we are restricted to the causal sequence. ![]() The region of convergence is defined based on the particular sequence x( n) being applied. (5.1), all the values of z that make the summation to exist form a region of convergence in the z-transform domain, while all other values of z outside the region of convergence will cause the summation to diverge. (5.1) is referred to as one-sided z-transform or a unilateral transform. Here, the summation taken from n = 0 to n = ∞ is in accordance with the fact that for most situations, the digital signal x( n) is a causal sequence, that is, x( n) = 0 for n < 0. ![]()
