Question
For the two-port network shown in the figure, the impedance () matrix (in ) is
Correct answer
(C) bmatrix 9 & 6 \ 6 & 24 bmatrix
Solution
The given network is a -network. We can find the -parameters first:
The -matrix is the inverse of the -matrix:
Thus, .
The -matrix is the inverse of the -matrix:
Thus, .
