The h-parameter h11 of a two-port is an input impedance measured with?

  • AOutput port short-circuited
  • BOutput port open-circuited
  • CInput port open-circuited
  • DBoth ports disconnected
Report an error
Correct Answer: A. Output port short-circuited
Explanation: From V1=h11 I1+h12 V2, setting V2=0 corresponds to an output short circuit, so h11=V1/I1 under that condition.
