| 摘 要： | 介绍了一种对光谱信号进行预处理的高低通综合滤波法，它对高频噪声和低频扰动分别采用不同的措施进行处理，高频噪声采取平滑滤波法进行去除，低频扰动采取低通数字滤波器进行去除，试验结果表明，这样做既去除了高频噪声和低频扰动，同时又保留了光谱的细节部分，最后，文中将高低通滤波法和带通滤波法的处理结果进行了比较。

| Abstract: | In this paper, a kind of high-low pass synthetic filter method for spectral preprocessing is described . This method adopts different measurement to process the high frequency noise or the low frequency disturbance . It is shown from experiments that the method can remove the high frequency noise and the low frequency disturbance, retain spectral details at the same time. Finally,comparison is made on the results of high-low pass filter and band pass filter. |
