For a positive-real function F(s), complex poles and zeros must occur in?

  • AUnrelated locations
  • BComplex-conjugate pairs
  • COnly the right-half plane
  • DOnly at s=0
Report an error
Correct Answer: B. Complex-conjugate pairs
Explanation: Because a positive-real network function is real for real s, nonreal poles and zeros occur in complex-conjugate pairs.
Reference: Standard network theory: conjugate roots
