abcd2z

Convert ABCD-parameters to Z-parameters

Syntax

z_params = abcd2z(abcd_params)

Description

z_params = abcd2z(abcd_params) converts the ABCD-parameters abcd_params into the impedance parameters z_params. The abcd_params input is a complex 2N-by-2N-by-M array, representing M 2N-port ABCD-parameters. The function assumes that the ABCD-parameter matrices have distinct A, B, C, and D submatrices:

z_params is a complex 2N-by-2N-by-M array, representing M 2N-port Z-parameters.

Examples

collapse all

Convert ABCD-parameters to Z-parameters. Define a matrix for ABCD-parameters.

A =      0.999884396265344 +  0.000129274757618717i;
B =      0.314079483671772 +      2.51935878310427i;
C = -6.56176712108866e-007 + 6.67455405306704e-006i;
D =      0.999806365547959 +  0.000247230611054075i;
abcd_params = [A,B; C,D];

Convert the result to Z-parameters.

z_params = abcd2z(abcd_params)
z_params =

   1.0e+05 *

  -0.1457 - 1.4837i  -0.1453 - 1.4835i
  -0.1459 - 1.4839i  -0.1455 - 1.4836i
