Measurement of voltage ratio at audio frequencies

Electrical Engineering, 1957
HIGH orders of accuracy in voltage-ratio measurements are becoming increasingly important in computer fields. Accuracies of 0.01% or better are desired. Equipment such as precision ratio transformers are used in these applications. However, methods have been lacking for verifying the ratios of this equipment to that accuracy at the desired frequencies ...
