The ABCD matrix for a two-port network is defined by :

$$\left[ {\matrix{ {{V_1}} \cr {{I_1}} \cr } } \right] = \left[ {\matrix{ A & B \cr C & D \cr } } \right]\left[ {\matrix{ {{V_2}} \cr { - {I_2}} \cr } } \right]$$

The parameter B for the given two-port network (in ohms, correct to two decimal places) is _______.

Consider a two-port network with the transmission matrix: T = $$\begin{bmatrix}A&B\\C&D\end{bmatrix}$$. If the network is reciprocal, then

The z-parameter matrix for the two-port network shown is $$$\left[ {\matrix{ {2\,j\,\omega } & {j\,\omega } \cr {j\,\omega } & {3\, + \,2\,j\,\omega } \cr } } \right]$$$ Where the entries are in $$\Omega $$. Suppose $$\,{Z_b}\,\left( {j\,\omega } \right) = {R_b} + j\,\omega $$ Then the value of $${R_b}$$ (in $$\Omega $$) equals _______________________3

The 2-port admittance matrix of the circuit shown is given by
