Question

How do you convert between ABCD parameters and impedance parameters?

Answer 1

To convert between ABCD parameters and impedance parameters, you can use the following formulas:

   - Impedance Parameters to ABCD Parameters: A = D = 1, B = Z11, C = Z21/Z11

   - ABCD Parameters to Impedance Parameters: Z11 = B, Z21 = C * Z11, Z12 = A/B, Z22 = D - (C * Z11)

Answer 2

To convert between ABCD parameters and impedance parameters, you can use the following formulas:

Converting ABCD to impedance parameters:

Calculate the impedance parameters as follows:

Z11 = A/C
Z12 = (A * B - D * C) / C
Z21 = 1 / C
Z22 = D / C

Converting impedance to ABCD parameters:

Calculate the ABCD parameters as follows:

A = Z11 / Z21
B = (Z11 * Z22 - Z12 * Z21) / Z21
C = 1 / Z21
D = Z22 / Z21

These formulas allow you to convert between the ABCD parameters and impedance parameters. Note that ABCD parameters represent a two-port network in terms of voltage and current relationships, while impedance parameters describe the same network in terms of impedance relationships.
