【摘要】 将混沌理论应用到弱信号的测量中已获得了初步的成功,降低因电子开关的频繁通断而引起的测量噪声是目前需要解决的主要问题。提出了一种新的混沌测量电路设计方法,它利用DSP仿真电子开关,与已有的测量方法相比,具有更好的线性度和更小的误差。给出了新方法与目前已有方法的测量结果对比,表明该方法具有更良好的前景。更多还原

【Abstract】 To detect the weak signal by using chaos theory has been succeeded in initiall. Reduce noise caused by frequently on/off of electronic switch is the chief problem which has to be solved .A new method of design chaotic measurement circuits is presented, it simulates the electronic switch by DSP. The new chaotic measurement system has better linearity and less error. The experiment results based on new method are given. Compareing with other methods, the new method has good properties in application.更多还原
