"Stochastic Resonance as Dithering," Phys. Rev. E (Statistical Physics),
Vol. 61, 2000 Jan., pp. 233-236.
A direct correspondence is demonstrated between
the phenomenon of "stochastic resonance" in static nonlinear systems and the dithering
effect well known in the theory of digital waveform coding. It is argued that
many static systems displaying stochastic resonance are forms of dithered quantizers,
and that the existence or absence of stochastic resonance in such systems can
be predicted from the effects of "dither averaging" upon their transfer characteristics.
Also, results are introduced regarding stochastic resonance in certain nonlinear
systems with memory (e.g., hysteretic systems).
