Abstract: Based on transmission line theory, the voltage transfer ratio function matrixes are derived for the multi-conductor cable system. Then an optimising object function for reducing crosstalk in the multi-conductor cable is established. The nonlinear programming is applied to optimize the terminal impedance load. According to the optimization results, a new method for reducing crosstalk is presented. Theoretical results are in good agreement with experimental ones. -
