Sensitivity of Multiconductor Cable Coupling to Parameter Variations

The sensitivities of multiconductor cable responses to uncertainties in wire position, line length and termination impedances are investigated by computing the response of a 13 conductor cable via the solution of the distributed parameter, transmission line formulation. It is found that the sensitivities to these parameter variations can be extraordinarily large for "high impedance terminations". The effect of parasitic wires in the bundle on the coupling between two wires is found also to be quite large for "high impedance loads" and relatively small for "low impedance loads".
