(choose chapter or problem)

The two-port network of Figure 17.1-1 has an input source \(V_{\mathrm{s}}\) with a source resistance \(R_{\mathrm{s}}\) connected to the input terminals so that \(V_1=V_{\mathrm{s}}-I_1 R_{\mathrm{s}}\) and a load resistance connected to the output terminals so that \(V_2=-I_2 R_{\mathrm{L}}=I_{\mathrm{L}} R_{\mathrm{L}}\). Find \(R_{\mathrm{in}}=V_1 / I_1, A_{\mathrm{v}}=V_2 / V_1, A_{\mathrm{i}}=-I_2 / I_1\), and \(A_{\mathrm{p}}=\) \(-V_2 I_2 /\left(V_1 I_1\right)\) by using the Z-parameter model.
