Determination of different parameters of Two-port network and verification of their interrelations 
A two port network is shown in the fig.1. Find the Z-matrix of the network.
The two port network P shown in fig.2 has ports 1 and 2, denoted by terminals (a,b) and (c,d) , respectively. It has an impedance matrix Z with parameters denoted by Zij. A 1Ω resistor is connected in series with the network at port 1 as shown in fig.2. The impedance matrix of the modified two-port network (shown as a dashed box) is
