在许多的数据采集系统中，现场的强电设备较多，不可避免

地会产生尖脉冲干扰,这种干扰一般持续时间短，峰值大，对这样

的数据进行数字滤波处理时，仅仅采用算术平均或移动平均滤波

时，尽管对脉冲干扰进行了1/n的处理，但，其剩余值仍然较大。

这种场合最好的策略是：将被认为是受干扰的信号数据去掉，这

就是防脉冲干扰平均值滤波法的原理。-In many of the data acquisition system, the scene of strong electrical equipment more, will inevitably produce sharp pulse interference, such interference Yi Ban short duration, peak large, the data on this digital filter processing, only the arithmetic mean or when the moving average filter, although pulse interference were 1/n of the treatment, but its residual value is still high. Such occasions the best strategy is: to be considered by the interference signal data to remove, which is the average filtering method against pulse interference principle.
