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.based on the theory of cic filter,the filter with fpga is simulated and synthesized,the results is given,and realizes it in the system of dvb-s.

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。
