摘要
提出了一种适用于强噪声背景下弱信号提取的一种非线性阻尼触发电路．讨论了构造该电路的基本物理模型．通过对双势阱系统触发机制的分析；表明其工作机理超出一般意义上的滤波抑噪和最佳检测范畴，从而达到抗强噪声干扰的目的。该电路模型可以方便地移植到相关的领域中．可望取得较好的应用前景。
In this paper a nonlinear damping trigger circuit under the strong noise background was presented.The basic physics model of the circuit construction is discussed.By analysising the trigger characteristic of the double well potential it is shown that its mechanisms is beyond the area of the general filter and optimum detection in the condition of strong noise disturbance.The circuit is very applicable to relevant area nad gets a good prosperity
