Question [3]: (13 Points) a) Discuss the importance of using different types of parameters to represent two-port networks. (2 Points) b) Discuss the different methods to deal with a two-port network inserted in a larger network. (2 Points) c) The Z-parameters matrix of the two-port nerwork shown in the figure below is given by: [(3+3/) [Z = 3 3. (3 + The load impedance Zi is adjusted for maximum average power transfer to Zi. If Z, is 311 and Ve is 10020 Volts: i) Using the Z-parameters, derive expressions for the currents entering the input and the output ports, I and I, as a function of the Z-parameters of the network, Z Z. and the voltage source Vg. ii) Calculate the percentage of the average power developed by the ideal voltage source Ve that is delivered to the input port i l'as well as the percentage that is delivered to the load impedance Z. (5 Points) (4 Points) Insert the results of part e) in a suitable Table. 12 Z. [Z] Z. V, V2 Vg
