Abstract

Background. The purpose of the study is to develop techniques for measuring three- and four-element resonant electrical circuit parameters. Materials and methods. Methods for aggregate measurements to determine electrical parameters (inductance, capacitance, and resistance) of three-element and four-element resonant electrical circuits are proposed. These are based on solving a system of equations, compiled with consideration of resonant frequency, quality factor, and maximum voltage measurements at the output of the measuring circuit at the resonant frequency. Results. Systems of equations to link target electrical circuit parameters with the measured frequency parameters are presented. Solutions to these equations being formulas for direct calculation of the required parameters are provided. Conclusions. The possibility of using the method for aggregate measurements to determine parameters of three- and four-element resonant electrical circuits is shown. 

Key words
