Answer» The connection of two 2-port networks is shown in the figure. The ABCD parameters of $N_{1}$ and $N_{2}$ networks are given as ${[\begin{matrix} A & B C & D \end{matrix}]}_{N 1}$ = $[\begin{matrix} 1 & 5 0 & 1 \end{matrix}]$ and ${[\begin{matrix} A & B C & D \end{matrix}]}_{N 2}$ = $[\begin{matrix} 1 & 0 0.2 & 1 \end{matrix}]$ The ABCD parameters of the combined 2-port network are
