Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Y parameters are also known as short circuit parameters.
In Y parameters input and output currents are represented in terms of input and output voltages.
I1 = Y11.V1 + Y12.V2
I2 = Y21.V1 + Y22.V2
Calculation:
To calculate Y21 input port should be short-circuited
Applying KCL at node V
V2 = 3.Va ----(1)
Also
Va = -I1 ----(2)
From equation (1) and (2) we get,
Important Points
|
Two Port Parameters |
Condition for Symmetry |
Condition for Reciprocal |
|
Z Parameters |
Z11 = Z22 |
Z12 = Z21 |
|
Y parameters |
Y11 = Y22 |
Y12 = Y21 |
|
ABCD parameters |
A = D |
AD - BC = 1 |
|
H parameters |
h11h22 - h12h21 = 1 |
h12 = -h21 |
