5 Derive the condition for symmetry and reciprocity of Y-parameters. (5)
6 What is h-parameters? Why they are called hybrid parameters? (5)
7 What is the differentiate between network analysis and synthesis. (5)
8 State the properties of LC driving point immittance function. (5)

‎PART B
Answer any two full questions, each carries 10 marks
9 For the circuit shown in Fig. 2 find the value of Ry that absorbs maximum (10)
power from the circuit and the corresponding power under this condition.

‎10 For the network shown in Fig. 3, draw the oriented graph, write the tie-set (10)

‎schedule and hence obtain the equilibrium equations on loop basis. Calculate the

‎values of branch current and branch voltages.
