Electromagnetic induction between power lines and telecommunication cables has been studied since early 1900’s [1]-[12], because such induced voltage may cause physical injury to service personnel, and malfunction of telecommunication equipment or

Common-mode voltage and current measurements are one of the key issues to solve EMC troubles in the field. Thus, there are several measurement probes have been developed to measure common-mode voltage and current of an electromagnetic disturbance [1]

Theoretical and experimental investigations were carried out on the characteristics of the shunt-type asymmetric artificial network (AAN). The findings are as follows: 1) The theoretical formulas for the differential- and common-mode impedances as we

Conducted asymmetric disturbances are measured at telecommunication ports of equipment under test using an asymmetric artificial network (AAN). Therefore, theoretical investigations are carried out to characterize an AAN with a mode-impedance matrix,

This study presents a hierarchical clustering-based assessment of audible noises at telephone terminals. In discriminating the electromagnetic interference (EMI) patterns of telephone-audible noises, both the time- and frequency-domains-based approac
