The thesis isdevoted to researching the possibilities of using simulated resonance effect for impendance measurement.
The thesis purpose consist in the research and development of means for the impedance measurement on the basis of simulated resonance effect, which are characterized by high accuracy, universality in using, simplicity of construction and practical application
The scientific novelty of the work consist in analyzing the general principles for implementation of simulated resonance method to the impedance measurement; in the synthesis and analysis of metrological simulator of impedance in Cartesian coordinates with advanced features; in the elaboration of the impedance measurement circuit based on simulated resonance effect in Cartesian coordinates; in the elaboration of balancing algorithms for this circuit and in the elaboration of Cartesian coordinates impedance meter.
Theoretical meaning consistsin the analysis of implementation principles of simulated resonance method for impedance measurement; in the application of oriented graphs method to the synthesis and analysis of metrological impedance simulator; in the elaboration and analysis of impedance meter structure with simulated resonance in Cartesian coordinates and of its functional algorithm.
Applicative value of the results. Based on the researches, the structure of the impedance meter with simulated resonance was developed for the high accurately measurement of impedance in Cartesian coordinates.
Implementation of research results. Based on the researches, they were developed two laboratory works to discipline Electronic measurements. The results are published in 17 scientific papers. 10 patents and 14 medals at international exhibitions were obtained.
