In the circuil of Fig. the equivalent impedance seen across terminals A. B is

For the 2-port network shown in Fig. determine the h-parameters. Using these parameters, calculate the output (port '2' ) $${v_2}$$, when the output port is terminated in a 3$$\Omega $$ resistance and a 1 V (DC) is applied at the input port ($${v_1}$$ = 1 V).

For a 2-port network to be reciprocal

Two two-port networks are connected in cascade. The combination is to be represented as a single two-port network. The parameters of the network are obtained by multiplying the individual
