A two-port network is defined by the following pair of equations i1 = 2V1 + V2 and i2 = V1 + V2. Its impedance parameters, \(\left[ {\begin{array}{*{20}{c}} {{Z_{11}}}&{{Z_{12}}}\\ {{Z_{21}}}&{{Z_{22}}} \end{array}} \right]\) are given by
1
\(\left[ {\begin{array}{*{20}{c}} 2&1\\ 1&1 \end{array}} \right]\)
2
\(\left[ {\begin{array}{*{20}{c}} 1&1\\ 1&2 \end{array}} \right]\)
3
\(\left[ {\begin{array}{*{20}{c}} 1&-1\\ -1&2 \end{array}} \right]\)
4
\(\left[ {\begin{array}{*{20}{c}} 2&-1\\ -1&1 \end{array}} \right]\)
