信号消噪处理研究

Study of the Methods of Reducing Noise

在模态试验中,无论激励信号还是响应信号,都有不同程度的噪声污染问题。噪声是使信号产生失真的误差源。文章对消除噪声的方法进行了详细的研究,得出针对各种不同信号的噪声处理办法,收到了良好的效果。

Noise pollution is a problem for both input signal and output signal in mode test. In order to obtain useful signal, have to deal with the noise. In this paper, the results of reducing noise show that the different signal has different method . The results of the research indicate the method is an effective means to resolve the common problem.
