Abstract

Background. The authors have developed an error estimating technique when determining the parameters of non-resonant multi-element circuits using the results of aggregate measurements.
Materials and methods. Causes of systematic (methodical and instrumental) and random errors of determining the parameters of non-resonant multi-element circuits are given. Error analysis with one-by-one variations of all circuit element parameters in fixed ranges of nominal values allows to determine ranges for permissible ratios of measurable circuit element parameters.
Results. The work shown steps of the technique and presents calculated ratios for estimating errors of determining the circuit parameters. The proposed method is applied for estimating errors when determining the parameters of non-resonant fourelement circuit with variation of all circuit element parameters in fixed ranges.
Conclusions. The possibility of applying the proposed methodology for estimating errors when determining the parameters of every circuit elements is confirmed on a practical example. 

Key words
