Examination of the demodulation effect of two-tone disturbances on nonlinear elements

J. Nitsch, N. Korovkin, and E. Solovyeva

Abstract. The effect of two disturbing sources with close frequencies on a nonlinear circuit is investigated. It is shown that low-frequency oscillations occur in such a circuit. These low-frequency oscillations represent a significant threat to the electronic equipment, since standard filters do not suppress low-frequency harmonics. On the basis of Picard’s iterations the synthesis of a protection system against low-frequency oscillations is performed.
