ABCD Parameter:
We know that the ABCD parameter of the transmission line
\(\left[ {\begin{array}{*{20}{c}} {{V_1}}\\ {{I_1}} \end{array}} \right] = \left[ {\begin{array}{*{20}{c}} A&B\\ C&D \end{array}} \right]\left[ {\begin{array}{*{20}{c}} {{V_2}}\\ { - {I_2}} \end{array}} \right]\ \)
A = D
AD – BC = 1
\(\left[{\begin{array}{*{20}{c}} A&B\\ C&D \end{array}}\right]\)= \(\left[\begin{array}{ll} 1 & 8 \\ 6 & 3 \end{array}\right]\)
So, B = 8
Conditions of reciprocity and symmetry in terms of different two-port parameters are:
|
Parameter |
Conditions of reciprocity |
Conditions of symmetry |
|
Z |
z12 = z21 |
z11 = z22 |
|
Y |
y12 = y21 |
y11 = y22 |
|
T(ABCD) |
(AD – BC) = 1 |
A = D |
|
h |
h12 = -h21 |
(h11h22 – h12h21) = 1 |
