Stochastic resonance is the nonmonotonic response of a system to stochastic excitation. Although this phenomenon is well known in signal processing technology, it is often perceived as paradoxical, because it contradicts the intuition that has been developed by the analysis of conventional linear systems where the ratio of the output signal-to-noise is the maximum in the absence of noise. Numerous manifestations and applications of stochastic resonance are known in physics, biology, medicine, mechanics and other fields.^1–21 For the first time, this phenomenon was mentioned by Benzi et al.^13–15 for the description of cyclically recurring glacial periods. In the 1980s, this phenomenon was considered as applicable to bistable systems with a periodic input signal and random noise. Later, it was discussed and used when studying a wider class of systems.^16–21

随机共振作为随机宽带激励的平均响应及其可能的应用

随机共振是系统对随机激发的非单调响应。尽管这种现象在信号处理技术中是众所周知的，但它通常被认为是自相矛盾的，因为它与通过分析传统线性系统而得出的直觉相矛盾，在常规线性系统中，输出信噪比为最大。没有噪音。随机共振的许多表现形式和应用在物理，生物学，医学，力学和其他领域中是已知的。^1–21 Benzi等人首次提到了这种现象。^13-15用于描述周期性重复的冰川期。在1980年代，这种现象被认为适用于具有周期性输入信号和随机噪声的双稳态系统。后来，在研究更广泛的系统类别时进行了讨论和使用。^16–21
