Construction of mathematical models of contact radio interference under irradiation of a variable contact operating in a nonlinear mode for solving applied problems of ensuring an intra-system electromagnetic magnetic unit

The article discusses the modeling of contact noise generation processes in the design of electronic equipment, taking into account electromagnetic compatibility. The paper considers two types of contact jamming models. The main place is devoted to the analysis of a nonlinear model of contact noise formation. The analysis of a nonlinear model of the formation of contact radio interference, a nonlinear manifestation of the nature of contact resistance leads to a sharp increase in the frequency spectrum affected by contact noise. This is especially true for the case of irradiation of an alternating contact with a polyharmonic electromagnetic field while simultaneously operating on the radiation of several transmitters at once.
