s2tf - Convert S-parameters of 2-port network to 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 or power-wave transfer function of the network.

The following figure shows the setup for computing the transfer function, along with the impedences, voltages, and the power waves used to determine the gain.

The function uses the following voltages and power waves for calculations:

The impedances in the figure are optional arguments to the s2tf function which defines them as follows:

The default value of these impedances is 50 ohms.

The optional option argument determines the definition of the transfer function. option can be:

The default value of option is 1.
