Abstract

Electric analog circuits are used to simulate stochastic resonance (SR) systems. It is found that the signal-to-noise ratio (SNR) obtained by the SR device can exceed the upper limit of the SNR obtained by the optimal linear filter. By applying two SR devices successively, the SNR obtained by the SR devices may be about eight times larger than that of the optimal linear filter.
