| 摘 要： | 介绍了一种高性能的模拟自适应陷波器(ANF)的工作原理,电路结构及实验调整的结果。这种陷波器是从同类型的数字自适应陷波器演化而得到的,它的结构简单,调整方便,性能优良,不仅能适应于干扰为单一频率的场合,而且当干扰为复杂波形时也同样有效。这种模拟自适应陷波器特别适宜用作对随钻测量(MWD)信号的处理,以滤除信道的强干扰。

| Abstract: | The principle,circuit structure and experimental results of a new analog adaptive notch filter (ANF) are presented in this paper.The new analog ANF is developed on the basis of the same tvpe of digital ANF.It is of simple structure,easy adjustment and good performance.It can be used to filter single frequency interference and complex wave form interference.It is particularly suitable for processing signals from a measuring system during well drilling (MWD system) to filter the strong interference of the mud channel. |
