Xi′an Node Science Technology Co.Ltd.,Xi′an,710075,ChinaAbstract:In this paper,a new variable interpolated filter in DVB-S(Digital Vidoe Broadcast by Satellite) is introduced based on the common filter of cascaded integrator comb.Firstly a CIC filter module with interpolation factor 2 is designed,then we could reuse the basic module according to the interpolation factor.

摘 要：在数字上变频中常用的CIC滤波器的基础上，提出了一种适用于DVB-S系统的可变插值率CIC滤波器的实现结构，首先实现一个内插因子为2的CIC滤波器单元，然后根据不同的内插因子要求，来重复地调用这些内插因子为2的基本滤波器模块，这种CIC滤波器的实现结构符合结构化的设计思想。
