中文摘要：

随机共振作为一种新颖的信号处理手段在各个领域得到了广泛应用，在随机共振的基础上讨论了级联随机共振的构成方式，采用模拟电路的形式对其进行实现，并基于该电路构成嵌入式变尺度级联随机共振系统。此系统硬件采用ETX技术，可以对CPU主板功能进行全新整合，软件上通过定制XPE操作和采用EWF技术，加强了系统的稳定性，同时变尺度算法和最佳级联随机共振判断程序在系统中的移植可以使之在较高频率的场合准确应用。最后给出了应用实例，验证了该系统对信号提取的准确性。

英文摘要：

Stochastic resonance is a novel signal processing method that has been applied in some areas, based on which, the form of concatenation stochastic resonance is discussed in this article, and the scale transformation concatenation stochastic resonance system is found based on the concatenation stochastic resonance circuit. The ETX technology is adopted to integrate the CPU main-board functions and through customizing XPE system and adopting the EWF technique, the stability of the system is enhanced; the scale transformation and the judgment flow of the optimal concatenation stochastic resonance are transplanted into the system, which can make the system to be applied in a higher frequency occasion. At the end an example is given to identify the accuracy of the scale transformation concatenation stochastic resonance system.
