摘　　要：在数字信号处理的许多场合中,信号的采样数据在进一步分析之前必须平滑处理。理论上,有许多低通滤器可以执行这一工作,其中叠代移动平均最简单且最易于实现。对叠代移动平均的一些特性进行了分析,并根据它在平滑离散周期数据中的应用进行了讨论。In digital signal processing there are many cases where the sampled data of the signal should be smoothed before any subsequent process. Theoretically there are many kinds of lowpass filters which can carry out such a task, among them iterative moving average is the simplest one and is very easy to implement. In this paper we analyse some properties of iterative moving avergae and discuss its application in smoothing discrete periodic data.
