Abstract :
The features of a four-coaxial line are recalled and an original compensation technique that reduces the voltage or current transmission error to below 10/sup -10/ at low frequency is presented. Active circuits suitable for the reproduction of EMFs or impressed currents of real generators within a high-precision measuring system even in loaded condition are shown.
