DEVICE FOR THE DETERMINATION OF THE DIGITAL EQUIVALENT OF AN UNKNOWN ANALOGUE VOLTAGE ELECTRIC

摘要

The invention is appropriate for use in analogue-to-digital converters (ADC) with high resolution in the electric power measurement technique. The invention uses the principle of double integration, such as the analogue Integrator is replaced with reversible counter (4) excludes the disadvantages of analogue integration and preserves the noise immunity converter. In the device using a converter with discreet integration (2). The result of the conversion is invariant with respect to the modification of the parameters of the converter with discreet integration. The accuracy of the conversion is determined by the accuracy of the reproduction of the reference voltage UE, and the resolving ability of digit capacity of the meter (6). The invention is appropriate for use as ADC to which there is no requirement for performance. The invention is suitable for application in the reference measuring instruments.
