摘      要：The signal to noise ratio (SNR) obtained by the devices for manifesting stochastic resonance (SR) can be larger than that by the optimal linear filter. The essential reason for this fact is that there is an energy transfer from noise to signal under the SR condition which is absent in the linear case.
