The root locus method, a pole of a transfer function G(s) is the value of s for which G(s) approaches ___________________?
Correct answer: D. ∞
- A. -1
- B. 0
- C. 1
- D. ∞
Explanation
A pole is a value of s at which the transfer function becomes unbounded, so G(s) approaches infinity. This is distinct from the root-locus condition, where the closed-loop characteristic equation is satisfied.
