A parallel-series connection of two-port networks is shown in Fig. 5. $I_2$ +\ $Z_{11} = 25 \Omega$ $Z_{12} = 20 \Omega$ $Z_{21} = 5 \Omega$ $Z_{22} = 10 \Omega$ $I_1$ +\ $V_1$ $V_2$ -\n$Z_{11} = 50 \Omega$ $Z_{12} = 25 \Omega$ $Z_{21} = 25 \Omega$ $Z_{22} = 30 \Omega$ Fig. 5 A complex network (1) Analytical part (8 marks): Find the admittance [g] parameter. (2) Recording of analysis (2 marks): Write up in your laboratory book a detailed account of your analysis. Discuss with your lab partner what kind of connection (e.g. series, parallel or cascade?) is additive for z parameters, additive for y parameters and multiplicative for transition parameters.
