Question
In the h-parameter model of the 2-port network given in the figure shown, the value of (in S) is ______ .
Correct answer
1.24 to 1.26
Solution
The h-parameter is defined as the output admittance when the input port is open-circuited (). By opening port 1 and applying a test voltage at port 2, we calculate the equivalent resistance seen from port 2. For the given lattice/bridge network, the calculation yields an equivalent resistance of .
Therefore, the output admittance is:The correct range is 1.24 to 1.26.
Therefore, the output admittance is:The correct range is 1.24 to 1.26.
