Numerical Analysis of Stochastic Resonance by Method of Stochastic Energetics

Abstract

Stochastic resonance (SR) is numerically analyzed by the method of stochastic energetics. The work done by the external agent which drives the potential to fluctuate periodically is shown to be a good quantitative measure to detect SR. On the other hand, signal-to-noise ratio (SNR) is shown to be not a good quantitative measure of SR by comparison with the work.
