Abstract
The phenomenon referred to as stochastic resonance may improve the performance of signal detection devices. In digital signal processing, the effect of stochastic resonance depends on the sampling frequency. Thus, when applying stochastic resonance to digital signal processing, the sampling frequency to achieve high-performance signal detection must be determined. This paper elucidates the sampling frequency dependence of the stochastic resonance effect. It is found that the signal-to-noise ratio obtained by stochastic resonance becomes almost saturated as the sampling frequency is increased.
