The impedance matrices of two, two-port networks are given by
3 2 
and 15 5 2 3 5 25
If these two networks are connected in series, the impedance matrix of the resulting two port network will be—
-
-
3 5 2 25 -
18 7 7 28 -
15 2 5 3 - Intermediate
-
Correct Option: B
The given matrices are:
| and | ||||
| 2 | 3 | 5 | 26 |
When the two networks are connected in series the resulting impedance matrix is given by:
| + | = | ||||||
| 2 | 3 | 5 | 26 | 7 | 28 |
