General formula - opracowanie

General formula For every impedance Z we have a corresponding admittance Y = 1/Z. It is easy to show,
and should be taken as an exercise, that in admittance terms the formula 2.65 for input
conditions becomes
YI
Y0
=
YL cos βl + jY0 sin βl
Y0 cos βl + jYL sin βl
(2.71)
This turns out to have the same form as equation 2.65 with all Z changed into Y .
