用模拟电路的方法对随机共振现象进行多方面的实验研究,讨论随机共振机制,测量输出信噪比(SNR),由于在随机共振过程中部分噪声能量可转变为信号能量,利用这个机制可能在强噪声对信号的抑制下取出信号。Stochastic resonance (SR) phenomena are investiged from various aspects by utilizing an electric circuit The mechanism of SR is discussed and the output signal-to-noise ratio (SNR) is measured. The signal may be extracted from strong noise due to energy transfer from noise to signal under the SR condition.
