Low SNR Singal Recovery System Based on Stochastic Resonance

Abstract:

Stochastic resonance (SR) enhances the nonlinear system behavior with the assistance of noise. The energy-transfer mechanism makes the weak information revealed in the output spectrum, while the time-waveform is distorted. In this article, The Principle of stochastic resonance and recovery method are proposed and based on which, The nonlinear circuit is formed.At last, some examples are given to identify the performance of this nonlinear circuit.
