How do you find the region of Convergence in z-transform?
For x(n)=δ(n), i.e., impulse sequence is the only sequence whose ROC of Z-transform is the entire z-plane. If x(n) is an infinite duration causal sequence, then its ROC is |z|>a, i.e., it is the exterior of a circle of the radius equal to a.
What is meant by region of Convergence in z-transform?
Region of convergence. The region of convergence (ROC) is the set of points in the complex plane for which the Z-transform summation converges.
How do you find the region of Convergence?
Perhaps the best way to look at the region of convergence is to view it in the s-plane. What we observe is that for a single pole, the region of convergence lies to the right of it for causal signals and to the left for anti-causal signals.
What is region of Convergence in z-transform of unit step function?
Explanation: h[n] =u[n] Hence, Region of Convergence is the region for which the values of the roots in z transform are lying in the function and is the range of values of z for which |z|>1.
