Modeling and analysis of the effects of electrical contact degradation on high-speed signal transmission

Abstract

Electrical contact failures may alter the signals that are being transmitted and is one of the major causes of system failure. In this letter, an equivalent model of the connector with a degraded contact surface is developed and its transmission characteristics are analyzed. The effects of electrical contact degradation on high-speed digital signal transmission are studied. And the experimental results verify the theoretical analysis. The results of this letter are helpful in developing a better understanding of high-speed connection devices, and provide a theoretical support to identify failure features in fault diagnosis.
