摘要
通过双阈值系统中的随机共振特性,研究含有高斯白噪声的信号。在一定条件下,由于系统、信号和噪声的协同作用而产生随机共振现象,并通过某一噪声强度下的信号增益及信噪比增益表现出来。最后,通过MATLAB仿真演示了信号增益和信噪比增益与输入噪声强度的关系。
It is investigated the characteristics of stochastic resonance of the signal added Gaussian white noise in a bithreshold system. Stochastic resonance occurs in a certain case due to the cooperation of the system, signal and noise; and it is demonstrated by the signal gain and the signal-to-noise ratio gain in a certain noise. It demonstrated the relation of the signal gain and the signal-noise-ratio gain and the input noise intensity through the MATLAB simulation.
