Low-Order and Causal Twisted-Pair Cable Modeling by Means of the Hilbert Transform

摘要

A new low-order and causal twisted-pair cable model for the copper access network is derived. From the serial resistance of the widely used, but non-causal, BTO model, the serial inductance is computed via the Hilbert transform. By doing so, a causal cable model is obtained containing fewer parameters compared to the BTO model. The deviation between the two models is evaluated for the standardized ETSI cables.
