Дробно-линейное уравнение измерений

Abstract

The properties of wide-band measuring devices constructed on the basis of only linear transducers and having a linear fractional measurement equation are considered. A linear fractional measurement equation that provides no redundancy of error at quantization in the entire measuring range is established. Expression of criterion for the generalized evaluation of a wide- range device by its accuracy and measurement range is obtained. It is applicable for all measuring devices with linear fractional measurement equation (including linear equation) in which the analog-to-digital converter (ADC) with linear scale as quantizer is used. The position of linear fractional measurement equations in the classification of direct measurement methods is specified.
