摘要
研究了具有指数形式关联的两白噪声驱动下单模激光线性模型受信号调制后的输出信噪比 ,发现了随机共振现象。根据计算结果讨论了噪声 (噪声强度、噪声间互关联程度和关联时间 )和信号 (信号频率和信号强度 )
A stochastic resonance (SR) phenomenon was observed by studying the output signal-to-noise (SNR) of the linear model of single-mode laser, which driven by two white noises correlated in the form of a exponential function. Moreover, the influence on SNR by noise (noise intensity, correlated strength and correlation time between noises) and signal (signal frequency and signal strength) was discussed.
