Abstract(in English) | Ferrite cores are commonly used to reduced the radiated emissions from electronic information devices and also to improve the system immunity, while the effects for the latter case are not being fully elucidated. This is due to lack of understanding on the load effect produced by a ferrite core attachment. From this viewpoint, we previously analyzed the load effect caused by attachment of the ferrite cores to a cable or a wire above a ground plane, and proposed equivalent circuits for the load effect. In this paper, a two-wire transmission line with the ferrite core attachment was analyzed to obtain an equivalent circuit for the load effect. Under the assumption that the ferrite core attached to the lines acts only on the common-mode transmission, the resultant equivalent circuit was derived. Based on this finding, the far-end and near-end crosstalk between the two-wire transmission line was calculated from the transmission line theory, which was confirmed experimentally. |
