If all the poles of H(z) are inside the unit circle, then the system is said to be:
A. Only causal
B. Only BIBO stable
C. BIBO stable and causal
D. None of the mentioned
Answer:A
If all the poles of H(z) are inside the unit circle, then the system is said to be:
A. Only causal B. Only BIBO stable C. BIBO stable and causal D. None of the mentioned
Explanation: If all the poles of H(z) are inside an unit circle, then it follows the condition that |z|>r < 1, it means that the system is both causal and BIBO stable.
