Litvikh V. Methods of true RMS wide-band voltmeter's accuracy improvmant

The subject of inquiry - wideband true RMS voltmeters. The investigation is aimed at metrological and technical characteristics of wideband true RMS voltmeters. As methods of investigation there were used numerical methods, methods of theory of random processes, methods of theory of signal & circuit theory as well as bread- board and experimental models. Theoretical results and novelty lie in developing theory of structural-algorithmic methods of accuracy improving with reference to AC voltmeters. Practical results and novelty are devices of high technical and metrological characteristics. The the following devices: В3-48А, В3-59, ВК3-64, ВК3-65, ВК3-66, ВК3-68 were implemented at PO "RET", Tallinn, Estonia. The field of use - electro measuring technique.
