Fourier transform of signal induced in circuits with soft ferrite cores

Abstract

Frequently the distortions in an inductive circuit are analyzed and characterized by the ration between the amplitude of the superior harmonics of the induced signal and the amplitude of the first harmonic. More often the second and the third harmonics are considered. The paper tries to demonstrate to importance which must be done to the superior harmonic in order to characterize the response and magnetic properties of the soft ferrite core.
