A causal rational continuous-time LTI system is BIBO stable if all its poles lie?

  • AStrictly in the left half of the s-plane
  • BStrictly in the right half-plane
  • COnly on the jω-axis
  • DAt the origin only
Report an error
Correct Answer: A. Strictly in the left half of the s-plane
Explanation: For a causal rational system, BIBO stability requires the jω-axis to lie in the ROC, which means all poles must be strictly in the left half-plane.
