ABCD Parameter defines for two-port network
\(\left[ {\begin{array}{*{20}{c}} {{{\rm{V}}_{\rm{1}}}}\\ {{{\rm{I}}_{\rm{1}}}} \end{array}} \right] = \left[ {\begin{array}{*{20}{c}} {\rm{A}}&{\rm{B}}\\ {\rm{C}}&{\rm{D}} \end{array}} \right]\left[ {\begin{array}{*{20}{c}} {{{\rm{V}}_{\rm{2}}}}\\ {{{\rm{I}}_{\rm{2}}}} \end{array}} \right]\)
V1 = A V2 + B I2
I1 = C V2 + D V2
V1 = Input voltage
V2 = Output voltage
I1 = Input current
I2 = Output current
A, B, C, D = T-parameter
Calculation:
according to the diagram
V1 = A V2 + B I2
V1 = -5I2 + V2
Compare both equations
A = 1
