Mathematical model of the combination of information signals and multicomponent interference at the input of track devices of tone rail circuits

Abstract

Modern rail circuits are exposed to many factors that ultimately lead to the distortion of informational signals. In regular operation, the main factor of distortion is electromagnetic interference, both natural and artificial. The composition and characteristics of this interference vary over time very quickly and unpredictably. The functional safety of tone rail circuits requires compliance with the same indicators regardless of the current interference situation.
