s2y用法

zw123

请问在用s2y命令时，s是以dB为单位的，还是用实部+虚部形式的？

Convert S-parameters to Y-parameters

Syntax

y_params = s2y(s_params,z0)



Description


y_params = s2y(s_params'z0) converts the scattering parameters s_params into the admittance parameters y_params. The s_params input is a complex n-by-n-by-m array, representing m n-port S-parameters. z0 is the reference impedance; its default is 50 ohms. y_params is a complex n-by-n-by-m array, representing m n-port Y-parameters
