Reason (R): For a rational system, ROC is bounded by poles
A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true bit R is NOT the correct explanation of A
C. A is true but R is false
D. A is false but R is true
Answer:B
Reason (R): For a rational system, ROC is bounded by poles
A. Both A and R are true and R is the correct explanation of A B. Both A and R are true bit R is NOT the correct explanation of A C. A is true but R is false D. A is false but R is true
Explanation: For the rational transfer function H (z) to be causal, stable and causally invertible, both the zeroes and the poles should lie within the unit circle in the z-plane. For a rational system, ROC is bounded by poles.
