摘要: Stochastic resonance1,2,3 is often defined as a noise-induced rise (and then fall, for higher noise intensities) of the signal-to-noise ratio (SNR) weak narrow-band signal in nonlinear system. Various applications this phenomenon are being explored, particular possibility that stochastic resonance might help enable biological cells to respond 50-60-Hz electromagnetic fields, far below thermal level4,5. We therefore feel its place within broader physics context should be specified more clearly. Specifically, what can, and cannot, expected do.
