INHOMOGENEOUS FLUCTUATION DISTRIBUTION IN THE OUTPUT OF STOCHASTIC RESONANCE SYSTEMS AND ITS APPLICATION 下载免费PDF全文
Inputting a periodic signal mixed with white noise into a bistable system, we find that the fluctuation distribution in the time series of the output is strongly inhomogeneous. In certain phase part fluctuation is very low under the stochastic resonance condition, and consequently, the signal-to-noise ratio (SNR) there is much higher than that of the input. This mechanism can be used to design a nonlinear receiver to extract the signed from noise with SNR three times higher than the largest SNR obtained so far by the optimal linear filter. 相似文献

交流电桥实验,在无外界干扰或外界干扰很小的条件下,重复性好,数据稳定,实验的偶然误差可以忽略。因此,本文着重对交流电桥实验的系统误差和仪器选择,以图1所示的串联电容电桥为例,做些具体的讨论。 相似文献
