A two-port network has the Z-Matrix of $\begin{bmatrix} 10 & 5 \ 5 & 15 \end{bmatrix}$. If the impedance $Z_3$ equals to $2Ω$, what will be the total series impedance?
💡 Hint: Sum all the impedances found in the Z-Matrix.
Design a simple circuit using these impedances: $Z_{11} = 12Ω$, $Z_{12} = 3Ω$, $Z_{21} = 3Ω$, $Z_{22} = 8Ω$. Explain how you would configure it in a real scenario.
💡 Hint: Visualize how you'd connect these impedances in series to create a working circuit.
