The region of convergence of the z-transform of a unit step function is:
A. |z|>1
B. |z|<1
C. (Real part of z)>0
D. (Real part of z)<0
Answer:A
The region of convergence of the z-transform of a unit step function is:
A. |z|>1 B. |z|<1 C. (Real part of z)>0 D. (Real part of z)<0
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.
