摘要
针对现在的数字记录仪主要嵌入的是频域分析软件,而对于时域的特征点重视不够的缺点,着重分析了在时域内寻找这些特征点的方法。为了有效滤去信号中含有的噪声并便于寻找特征点,采取了分段数据拟合的方法。实验结果证明了文章方法的有效性。
For most data recorder parenthesis frequency-field analysis software don't pay attention to character dots in time-field. Seeking these dots is aimed in this paper. In order to filter noises rapidly and effectively and help to seek the characteristic points, data fitting of segments is atopted. Experimental results demonstrate the feasibility of the proposed method.
