Zhangkun, Theoretically speaking, NEXT and FEXT are definitely defined in time domain. In frequency domain, they were called coupling coefficient. Far-end coupling coefficient strongly depend on coupling length, frequency and matching condition. The couplind structure will behave resonance at some frequency. You might describe your condition in detail. Sogo Hsu Ph.D. Foxconn --- Zhangkun <zhang_kun@xxxxxxxxxx> ���T���G> Dear all > Now, we are analyzing the crosstalk between > transmission line.
