High-Precision Automatic Digital AC Bridge
Wolfgang Helbach, Peter Marczinowski, Gerhard Trenkler · IEEE Transactions on Instrumentation and Measurement · 1983
This paper deals with a high-precision automatic digital ac bridge including a digital detector as an integral part of the bridge. The resolution and systematic errors of this type of bridge are formulated. An automatic method to reduce the errors caused by the differential nonlinearity is described.
