The z-parameter equation for port 1 of a two-port network is?

  • AV1=z11 I1+z12 I2
  • BI1=z11 V1+z12 V2
  • CV1=z11 V1+z12 V2
  • DI1=z11 I1+z12 I2
Report an error
Correct Answer: A. V1=z11 I1+z12 I2
Explanation: By definition of impedance parameters, V1=z11I1+z12I2 and V2=z21I1+z22I2.
Reference: Standard network theory: two-port networks
