| Abstract: | The signal to noise ratio(SNR)obtained by the devices manifesting stoeha- stic resonance is compared with that obtained by the optimal linear filter.With the adiabatic approximation the former is always lower than the latter.Beyond the adiabatic approximation the former can be higher than the latter in cerain regions of input noise strength. |

| Keywords: | Stochastic resonance optimal filter adiabatic approximation |
