Crosstalk variations caused by uncertainties in three-conductor transmission lines

The crosstalk is a very important aspect of cable EMC (electromagnetic compatibility) performance evaluation. As uncertainties are introduced during cable fabrication and installation process, deterministic prediction methods are not suitable for a good estimation of the cable performance. This paper is focused on predicting the crosstalk of cable bundles by considering the uncertainties introduced in three-conductor transmission lines. How the uncertainties of different parameters in three-conductor transmission lines might affect the crosstalk and its variations are investigated and a better understanding on how to avoid high crosstalk in applications is obtained and presented.
