Aiming at these problems, this paper presents an efficient algorithm which use all zero digital filter for filtering the periodic component.
针对这两方面的问题，提出了一种用全零点数字滤波器滤除周期性分量的滤波算法。

The article discusses a periodic interference cancellation system based on adaptive filter theory, and introduces the system form and structure principle.
文中讨论了一种基于自适应滤波原理的周期性干扰对消系统，介绍了系统组成及结构原理。
