Frequency Balance Influence to Signal-to-Noise Ratio of Bistable Stochastic Resonance in Signal Smart Regression Recognition Procedure

Abstract

Systematic frequency holds great influence to bistable stochastic resonance (BSR) model. In this paper, frequency parameter f0 was investigated to explore the parameter-induced bistable stochastic resonance characteristic according to the former research results. Within a variable frequency parameter f0 range (from 0.01 to 10), a systematic output stochastic resonance emerged with the value change of frequency parameter f0. Systematic output signal-to-noise ratio (SNR) curve shows that the variable frequency parameter f0 could induce stochastic resonance in real-time signal analysis field
