New features and changes introduced in this version are:

• Function Added

• Methods Added

• Demo Added

Function Added

The makepassive function creates passive S-Parameters from any S-parameter array. Use this function to enforce strict numerical passivity on an array of S-parameters that represents a passive device.

Methods Added

Two new methods for rfmodel.rational objects are available:

• The ispassive method tests global passivity of an rfmodel.rational object.

• The stepresp method calculates the response of an rfmodel.rational object to a step signal. You can use this function to perform time-domain reflectometry (TDR) and time-domain transmission (TDT) analysis.

Demo Added

The Modeling a High-Speed Backplane (Part 3: 4-Port S-Parameters to Differential TDR and TDT) demo shows how to perform time-domain reflectometry (TDR) and time-domain transmission (TDT) analysis on network data.
