瞬变电磁法仪器研制中的噪声抑制问题

The problem of eliminating noise in developing TEM instrument

    摘要
  • 摘要: 归纳了瞬变电磁法仪器研制中所涉及的几种主要干扰类型。针对各类噪声的特点,分析了50Hz工频电噪声、本机噪声及高值噪声的抑制方法。特别指出了适度性原则下,采样率、观测时间及衰减窗口的匹配关系。

     

    Abstract: The main kinds of noises are summarized, and the methods of canceling 50Hz AC and white noise as well as high amplitude noise are analyzed according to their features in developing TEM instrument.Meanwhile the relation is pointed out especially that sampling rate,sampling time and decay windows matching each other under propriety principle.
