以输入和输出信号的统计特性的估计为依据，采取特定算法自动地调整滤波器系数，使其达到最佳滤波特性的一种算法或装置。自适应滤波器可 自适应滤波器

以是连续域的或是离散域的。离散域自适应滤波器由一组抽头延迟线、可变加权系数和自动调整系数的机构组成。-The input and output signals of the statistical properties of the estimators for the basis, take the specific algorithm automatically adjusts the filter coefficients, so as to achieve the optimal filter characteristics of an algorithm or device. Adaptive filter adaptive filterIs continuous or discrete domain domain. Discrete domain adaptive filter is composed of a group of tapped delay line, a variable weighted coefficient and automatically adjust the coefficients of the mechanism.
