Z-transform:

  1. The ROC of X(z) of a two sided signal consists of a ring in the z-plane centered about the origin.

enter image description here

  1. $σ_1$ and $σ_2$ depend only on magnitude of z.

  2. As in the case of Laplace transform $σ_2 \Rightarrow ∞ $ for a right-sided sequence and $σ_1\Rightarrow 0$ for a …
