The properties of the method of frequency errors correction of input circuits within the range of nonlinear operation

Abstract

The paper concerns the method of the correction of frequency errors of input circuits, elaborated for correction of module errors and phase errors of linear input circuits. The method is implemented in the spectral domain in a programmed manner. The author presents the findings of experimental research which show the efficiency of the method in measurements of rms value of nonsinusoidal current within the range of linear and nonlinear processing characteristics of a current transformer.
