The transmission parameter matrix [T] for an ideal transformer with a turns ratio of n1 : n2 is given by

• A. \(\left[ \begin{matrix} \frac{n_1}{n_2} & 1 \\ 0 & \frac{n_2}{n_1} \\ \end{matrix} \right]\)
• B. \(\left[ \begin{matrix} \frac{n_1}{n_2} & 0 \\ 0 & \frac{n_2}{n_1} \\ \end{matrix} \right]\)
• C. \(\left[ \begin{matrix} \frac{n_1}{n_2} & 1 \\ 0 & -\frac{n_2}{n_1} \\ \end{matrix} \right]\)
• D. \(\left[ \begin{matrix} \frac{n_1}{n_2} & 0 \\ 1 & -\frac{n_2}{n_1} \\ \end{matrix} \right]\)
