【摘要】 本文通过中值滤波法去除信号中的毛刺,在保留信号特征的前提下使信号尽可能平滑,并运用最小二乘法对具有趋势的检测信号进行趋势去除,排除更多不稳定的因素,得到精确、平滑、稳定的波形数据。更多还原

【Abstract】 The burr of signal is moved by using the median filter in this paper,and the signal is smoothed as far as possible while retaining the characteristics of the signal. Then,the trend of detection signals is removed by the least squares method. Finally,the more accurate waveform data is obtained by eliminating much unstable factors.更多还原
