Find the impedance parameter equivalent of the given network where R = 3 Ω.
z11 = 8.200 ± 2% Ω
z21 = 0.022 ± 2% Ω
z12 = 0.022 ± 2% Ω
z22 = 8.200 ± 2% Ω
Explanation:
Consider the following circuit to get z11 and z21.
z11 = V1 / I1 = (3 + 3) + 3 || [(3 + 3) + 3 || (3 + 3 + 3)]
Solving this, we get z11 = 8.200 Ω.

z21 = V2 / I1 = z12 = 0.022 Ω
To get z22, consider the circuit given below.
