摘要
利用参数调节的方法,在随机时滞双稳系统中实现了随机共振.研究了时滞和反馈强度对系统的影响.对比了常规随机共振和参数调节随机共振的信噪比曲线,从而验证了参数调节随机共振在应用范围和性能上的优越性.
Using method of parameter tuning, Stochastic Resonance (SR) is realized in stochastic time- delayed bistable system. And the influence of time delay and feedback intensity on signal-to-noise (SNR) is studied as weU. Through the comparison of SNR curves of parameter tuning stochastic resonance (PSR) and conventional stochastic resonance, the advantage of PSR in application range and performance is proved.
