“…With regard to the research on influence of electrical contact on time domain signal, Ya et al [14] conducted computer simulations to analyze the influence of the magnitude of the contact impedance on digital signal transmission. Li et al [15] used Time domain signal reflectometry (TDR) to locate the degradation area of connectors. Dorsey et al [16] showed the performance of high speed data for sliding contact system that can transmit digital data up to 3Gbps using theoretical analysis and experimental testing.…”

“…Most of these studies were organized to analyze degradation characteristics in the frequency domain. Li et al used the time domain reflectometry (TDR) to locate degradation area of faulty connectors. Accordingly, the effect of contact degradation of electrical connectors on signal transmission was monitored both in the time and frequency domains for the purposes of the current investigation.…”

In this article, theoretical modeling and simulations are introduced to explore the contact failure characteristics for connectors both in time and frequency domains. The equivalent models are developed to describe the impedance performances of un‐degraded and degraded connectors with the time domain and frequency domain, respectively. The experiments using a Network Analyzer for time and frequency domains analyses are conducted to verify the proposed models. The measured results agree well with the simulation results in the time and frequency domains.

High-speed backplane connectors are extensively used in digital baseband communication circuits. Connector degradation may lead to deterioration of the integrity of digital signals and is one of the major causes of low communication quality. In this study, an accelerated test was used to produce degraded connector samples. Based on the degradation characteristics of the connector electrical contact surface, the differential transmission method was applied to enhance signal integrity in such degraded electrical contact circuits. Referring to the Gigabit Ethernet standard, the differential signal waveforms and eye diagrams of high-speed channels with un-degraded and degraded connectors were studied. Improvement of the circuit reliability by differential transmission was demonstrated from the perspectives of both experimental investigations and analysis using probability calculations.
