Two-Port (EE)

The $$Z$$ matrix of a $$2$$ $$-$$ port network is given by $$\left[ {\matrix{ {0.9} & {0.2} \cr {0.2} & {0.6} \cr } } \right].$$ The element $${Y_{22}}$$ vof the corresponding $$Y$$ matrix of the same network is given by

A passive 2-port network is in a steady state.Compare to its input, the steady state output can never offer

A two-port device is defined by the following pair of equations: $${i_1} = 2{v_1} + {v_2}$$ and $${i_2} = {v_1} + {v_2}$$ Its impedance parameters $$\left( {{z_{11}},\,\,{z_{12}},\,\,{z_{21}},\,\,{z_{22}}} \right)$$ are...

If a two-port network is passive, then we have, with the usual notation, the following relationship
