Study on Effect of Noise to Signal Transmission in A Circuit of Threshold-detector Contained A Comparator
【摘要】 本文研究了光电探测系统的比较阈值电路中的噪声对信号传输的影响。从理论上计算了该系统的输出自相关函数、功率谱密度和信噪比;分析了比较阈值电路中的随机共振现象;说明对非线性系统可以用噪声来增强信号的传输能力。
【Abstract】 The effect of noise on signal transmission is studied in a nonlinear circuit of threshold-detector contained a comparator. The theoretical analysis of autocorrelation function, power spectral density and ratio of signal-to-noise for output of the circuit showed that the nonlinear characteristics of the circuit is stochastic resonance which will be useful in applications for sensors, transducers or communication systems.
