Measurement of Four-Pair Admittances witk Two-Pair Bridges

The purpose of this paper is twofold: 1) to show how extrapolation techniques can be used to obtain well-defined and versatile measuring systems; and 2) to apply such techniques to the measurement of four-pair admittances with two-pair bridges. When four-pair admittances are large, measurements with two-pair bridges have limited precision, but with reasonably small admittances, measurement precision is essentially equal to that attained with four-pair bridges.
