For an ABCD parameter of a transmission line, which of the following is correct?
For an ABCD parameter of a transmission line, which of the following is correct?
Right Answer is:
AD − BC = 1
SOLUTION
ABCD parameters are also known as transmission line parameters.
We know that the ABCD parameter of the transmission line
$\left[ {\begin{array}{*{20}{c}} {{V_1}}\\ {{I_1}} \end{array}} \right] = \left[ {\begin{array}{*{20}{c}} A&B\\ C&D \end{array}} \right]\left[ {\begin{array}{*{20}{c}} {{V_2}}\\ { – {I_2}} \end{array}} \right]$
The symmetry condition for a two-port network in terms of transmission parameters is: A = D
The Reciprocity condition for a two-port in terms of transmission parameters is AD – BC = 1
