Final Value Theorem of Z-Transform. The final value theorem of Z-transform enables us to calculate the steady state value of a sequence x(n) x ( n), i.e., x(∞) x ( ∞) directly from its Z-transform, without the need for finding its inverse Z-transform. Statement - If x(n) x ( n) is a causal sequence, then the final value theorem of Z ...The Region of Convergence. The region of convergence, known as the ROC, is important to understand because it defines the region where the z-transform exists. The z-transform of a sequence is defined as.

Existance of Fourier transform does not imply existance of Z-transform, but the converse is true; i.e., existance of Z-transform (may) imply existing of Fourier transform (which is found by evaluating Z-transform on the unit circle) which requires that ROC includes unit circle.

Declare Equations. You can use the Z-transform to solve difference equations, such as the well-known "Rabbit Growth" problem. If a pair of rabbits matures in one year, and then produces another pair of rabbits every year, the rabbit population p ( n) at year n is described by this difference equation. p ( n + 2) = p ( n + 1) + p ( n) Declare ...
