Abstract
Investigated a method of measuring the integral characteristics on the instantaneous values of the input and additional harmonic signals. A method provides defining characteristics on instantaneous values of signals, measured simultaneously once per period at the moment of transition of one of the additional voltage through zero. The results of the analysis of influence of quantization of instant values of signals at the error of the result of the determination of informative parameters are shown. It is established that this type of error depends not only on the width of analog-to-digital converters but also the phase angle of the additional signals. The obtained results allow to determine the optimum angle of phase shift depending on the requirements of measurement accuracy.
