The Unger Model is an empirical standard model for near end crosstalk (NEXT) power spectra as experienced by communication systems over unshielded twisted pair (UTP). Twisted pair cables are usually grouped together in a binder where they experience crosstalk. Based on empirical observations, Unger 〔J. H. Unger, "Near-End Crosstalk Model for Line Code Studies", ECSA Contribution'', T1D1.3/85-244, November 12, 1985.〕 proposed that, at the 1% worst case, the NEXT power spectra , due to a single disturber, can be bounded by : while the NEXT power spectra due to 49 disturbers (full binder) can be bounded by : == References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Unger model」の詳細全文を読む スポンサード リンク
