Stochastic resonance in electrical circuits. II. Nonconventionalstochastic resonance

摘要

For pt.I see ibid., vol.46, no.9, pp.1205-14 (1999). Stochasticnresonance (SR), in which a periodic signal in a nonlinear system can benamplified by added noise, is discussed. The application of circuitnmodeling techniques to the conventional form of SR, which occurs innstatic bistable potentials, was considered in a companion paper. Here,nthe investigation of nonconventional forms of SR in part using similarnelectronic techniques is described. In the small-signal limit, thenresults are well described in terms of linear response theory. Somenother phenomena of topical interest, closely related to SR, are alsontreated
