Abstract

The present invention relates to an arrangement for analyzing transmission line properties. Measurement data providing means (10) provide data of a first frequency dependent line property, line property calculation arrangement (20) with model handling means (21 A), a Hubert transform handler (22) and line property determination means (23) calculate said first property based on model parameters, line resistance at 0 frequency, roc r cut-off frequency, v, line capacitance C∞r and line inductance Σ^. The line model handling means (21 A) calculates the line inductance L(J) via a Hubert transform of Q(f/v)r relating line resistance R(J) to roc such as formula (I). The Hilbert transform values are calculated using a parameterized closed form expression for the Hubert transform or they are tabulated. The line property determination means (23; 23A) calculates the first property and criteria function application means (40) uses the measured first property and the calculated first property for model parameters to find optimized numerical model parameter values.
