Спосіб вимірювання основних параметрів послідовних резонансних контурів

Abstract

The proposed method for measuring principal parameters of a series resonance circuit consists in connecting the resonance circuit in series with a reference resistor and measuring the phase shift between the voltages across the resonance circuit and the reference resistor at two different frequencies. Additionally, at one of the frequencies, the ratio between the amplitudes of the voltages across the resonance circuit and the reference resistor is measured. The parameters of the resonance circuit are determined from specified equations, using the results of the measurements. The proposed method provides for the possibility to determine the capacity, inductance, characteristic impedance, and other parameters of a resonance circuit.
