Convert Z-parameters to ABCD-parameters


abcd_params = z2abcd(z_params)


abcd_params = z2abcd(z_params) converts the impedance parameters z_params into the ABCD-parameters abcd_params. The z_params input is a complex 2N-by-2N-by-M array, representing M 2N-port Z-parameters. abcd_params is a complex 2N-by-2N-by-M array, representing M 2N-port ABCD-parameters. The output ABCD-parameter matrices have distinct A, B, C, and D submatrices:

Define a matrix of Z-parameters.

Z11 = -14567.2412789287 - 148373.315116592i;
Z12 = -14588.1106171651 - 148388.583516562i;
Z21 = -14528.0522132692 - 148350.705757767i;
Z22 = -14548.5996561832 - 148363.457002006i;
z_params = [Z11,Z12; Z21,Z22];

Convert to abcd-parameters

abcd_params = z2abcd(z_params)
abcd_params =

   1.0002 - 0.0002i   0.3151 + 2.5200i
  -0.0000 + 0.0000i   1.0001 - 0.0001i
