| 摘 要： | 本文以负压波信号采集滤波为例，介绍了基于LMS算法的自适应滤波器的基本原理和该滤波器几个关键参数设定的基本方法。实践证明，在采集随机不确定信号时，采用此滤波器进行信号调理具有比传统滤波器不可比拟的优越性。

| Abstract: | The working principle of an adaptive filter based on LMS algorithm and the key parameters validation are introduced in this paper. The application of this filter is discussed through a case of collecting negative pressure wave signals. Results show that, filter based on LMS algorithm is better than traditional ones in the signal modulation, especially for the random and indeterminate signals. |
