Abstract

Creation of non-linear radio engineering systems is the perspective direction. In radio engineering system as informational chaotic fluctuation is used. In work non-linear filtration of mix of chaotic fluctuation and noise is investigated. The non-linear filter contains the bistable system - Schmitt’s trigger and the edge filter. In the filter the effect of a stochastic resonance takes place. The signal at the exit of non-linear system amplifies with body height of intensity of noise to some of its best value. For narrow-band signals the effect of a stochastic resonance is investigated rather explicitly. Results of model operation are given in the Multisim program.
