Convert Y-parameters to ABCD-parameters


abcd_params = y2abcd(y_params)


abcd_params = y2abcd(y_params) converts the admittance parameters y_params into the ABCD-parameters abcd_params. The y_params input is a complex 2N-by-2N-by-M array, representing M 2N-port Y-parameters. abcd_params is a complex 2N-by-2N-by-M array, representing M 2N-port ABCD-parameters. The output ABCD-parameters matrices have distinct A, B, C, and D submatrices:

Define a matrix of Y-parameters.

Y11 =  0.0488133074245012 - 0.390764155450191i;
Y12 = -0.0488588365420561 + 0.390719345880018i;
Y21 = -0.0487261119282660 + 0.390851884427087i;
Y22 =  0.0487710062903760 - 0.390800401433241i;
y_params = [Y11,Y12; Y21,Y22];

Convert to ABCD-parameters

abcd_params = y2abcd(y_params)
abcd_params = 2×2 complex
