摘要
利用随机共振所得到的信噪比与最佳线性滤波器的信噪比进行比较,在绝热近似下前者低于后者,考虑对绝热近似的修正项,前者可以在某些输入噪声强度区间内超过后者.
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.
