C. Feasible solution
D. None of the mentioned
Answer:A
What is the set of all values of z for which X(z) attains a finite value?
A. Radius of convergence B. Radius of divergence C. Feasible solution D. None of the mentioned
Explanation: Since X(z) is a infinite power series, it is defined only at few values of z. The set of all values of z where X(z) converges to a finite value is called as Radius of Convergence(ROC).
