Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF2 Port network Parameters for hybrid parameters is defined as:
\(\left[ {\begin{array}{*{20}{c}} {{V_1}}\\ {{I_2}} \end{array}} \right] = \left[ {\begin{array}{*{20}{c}} {{h_{11}}}&{{h_{12}}}\\ {{h_{21}}}&{{h_{22}}} \end{array}} \right]\left[ {\begin{array}{*{20}{c}} {{I_1}}\\ {{V_2}} \end{array}} \right]\)
Given circuit:
I2 = h21 I1 + h22 V2
\({h_{21}} = {\left. {\frac{{{I_2}}}{{{I_1}}}} \right|_{{V_2} = 0}}\)
KCL at ‘P’
\({h_{21}} = \frac{{{I_2}}}{{{I_1}}} = \frac{{\frac{{ - {I_1}}}{2}}}{{{I_1}}}\)
\({h_{21}} = \frac{{ - 1}}{2} = \frac{{ - 1}}{2}\)
