The Y-parameters of a 2-port network are:
[Y] = 
5 3 
S 1 2
A resistor of I ohm is connected across as shown below. The new Y-parameter would be—
-
-

6 4 
S 2 3 -

6 2 
S 0 3 -

5 4 
S 2 2 -

4 4 
S 2 1

Correct Option: B
Y-parameter of 1 Ω resistor network are
| = det | ![]() | ![]() | ||||
| –1 | 1 |

| New Y-parameter = | ![]() | ![]() | + | ![]() | ![]() | ||||
| 1 | 2 | –1 | 1 |
| = | ![]() | ![]() | ||||
| 0 | 3 |
Hence alternative (B) is the correct choice.
