The main traditional methods for detecting signals are spectral analysis and averaging, but both the two methods have certain shortcomings and deficiencies: they can not be used to detect weak signals. Different from the traditional linear method,Stochastic resonance(SR) can not only wipe off noise but can also turn Parts of noise energy into signal energy to increase the signal-to-noise rate(SNR).In the past two decades, stochastic resonance theory and research continues to develop, and it has an outstandi...
