Nominal π method

qImage66d0a8ab588b6a2dcef68242

In the nominal π model, a medium transmission line is represented by a series of impedance and shunt admittances that are split between the sending end and receiving end of the line.

The ABCD constant for a medium transmission line using the nominal π method is:

\(\begin{bmatrix} A & B\\ C & D \\ \end{bmatrix} =\begin{bmatrix} \rm 1+\frac{\bar{Y} \bar{Z}}{2} & \rm \bar{Z}\left(1+\frac{\bar{Y} \bar{Z}}{4}\right) \\ \rm \bar{Z}\left(1+\frac{\bar{Y} \bar{Z}}{4}\right) & \rm 1+\frac{\bar{Y} \bar{Z}}{2} \\ \end{bmatrix} \)
