介绍了用模型法设计全极点ＩＲ滤波器的方法，并给出了用高速器件ＩＭＳＡ１００实现的例子。由于全极点ＩＲ滤波器只有极点，没有零点，因而用硬件实现时可以节省器件。
The method of designing the all-pole IR filter by the model method is introduced and the example of using the high-speed device IMSA100 is given. Since the all-pole IR filter has only a pole and no zero, the device can be saved when implemented in hardware.
