s2tf

Convert S-parameters of 2-port network to voltage transfer function

Syntax

tf = s2tf(s_params, z0, zs, zl,option)

Description

tf = s2tf(s_params, z0, zs, zl,option) converts the scattering parameters, s_params, of a 2-port network into the voltage transfer function of a 2-port system. The transfer function represents the normalized voltage gain of the system. The following figure shows the setup for computing the transfer function, and the impedances and voltages used to define the gain.

The impedances in the figure are optional arguments to the s2tf function and are defined as follows:

The default value of these impedances is 50 ohms.

The voltages in the figure are defined as follows:

The definition of the transfer function is determined by the optional option argument.

option can be

The default value of option is 1.
