摘要
将混有加性高斯白噪声的周期脉冲序列通过阈值系统,对其传输性质进行理论研究。以输入输出的信号幅度和信噪比增益来分析随机共振现象,通过调节各相关参数使系统、信号和噪声因协同作用而产生随机共振现象:在某一最优噪声强度下获得最大的信号幅度及信噪比的增益。
The transmitting property of the periodic pulse trains added to additive Gaussian white noise though a threshold system is considered theoretically. Input-output gains of signal amplitude and signal-to-noise are analyzed as measures of the phenomenon of stochastic resonance (SR). In a certain optimal level of the noise, the gains culminate, namely SR occurs for the co-operation of the system, signal and noise by adjusting the parameters concerned.
