Audio-frequency analysis of inductive voltage dividers based on structural models

A binary inductive voltage divider (BIVD) is compared with a decade inductive voltage divider (BIVD) in an automatic IVD bridge. New detection and injection circuitry was designed and used to evaluate the IVDs with either the input or output tied to ground potential. In the audio frequency range the DIVD and BIVD error patterns are characterized for both in-phase and quadrature components. Differences between results obtained using a new error decomposition scheme based on structural modeling, and measurements using conventional IVD standards are reported.<>
