Two identical two-port networks having transmission matrix \left[ {\begin{array}{*{20}{c}}
{\text{A}}&{\text{B}} \\
{\text{C}}&{\text{D}}
\end{array}} \right] are cascaded. What will be the resultant transmission matrix of the cascade?
A.
\left[ {\begin{array}{*{20}{c}}
{\text{A}}&{\text{B}} \\
{\text{C}}&{\text{D}}
\end{array}} \right]
B.
\left[ {\begin{array}{*{20}{c}}
{{\text{2A}}}&{{\text{2B}}} \\
{{\text{2C}}}&{{\text{2D}}}
\end{array}} \right]
C.
\left[ {\begin{array}{*{20}{c}}
{{{\text{A}}^2} + {\text{BC}}}&{{\text{AB}} + {\text{BD}}} \\
{{\text{AC}} + {\text{CD}}}&{{\text{BC}} + {{\text{D}}^2}}
\end{array}} \right]
AnswerD.
\left[ {\begin{array}{*{20}{c}}
{{{\text{A}}^2}}&{{{\text{B}}^2}} \\
{{{\text{C}}^2}}&{{{\text{D}}^2}}
\end{array}} \right]
