Multiple choice

For the lattice shown in the figure, Za = j2$\Omega$ and Zb = 2$\Omega$. Calculate the values of the open circuit impedance parameter [z] = $\left[ \begin{array} \ Z_{11} & Z_{12} \\ Z_{21} & Z_{22} \end{array} \right]$.

  1. $\left[ \begin{array} \ 1-j & 1+j \\\\ 1+j & 1+j \end{array} \right]$
  2. $\left[ \begin{array} \ 1-j & 1+j \\\\ -1+j & 1-j \end{array} \right]$
  3. $\left[ \begin{array} \ 1+j & 1+j \\\\ 1-j & 1-j \end{array} \right]$
  4. $\left[ \begin{array} \ 1+j & -1+j \\\\ -1+j & 1+j \end{array} \right]$
