摘　　要：CIC抽取滤波器是无线通信中的常用模块,一般用于数字下变频(DDC)系统中。它可以在降低采样速率的同时,完成低通滤波的作用。本论文介绍了CIC抽取滤波器的工作原理,并给出了CIC滤波器的MATLAB程序及仿真结果。最后,利用FPGA高速、高稳定性的特点,在QUARTUS设计环境下进行了CIC滤波器的HDL模块设计。CIC extraction filter is commonly used as wireless communication module, generally used in digital down converter （DDC） system. It can finish the function of low pass filter when reducing the lower sampling rate at the same time. This paper introduces the working principle of CIC extraction filter, and gives the CIC filter MATLAB and the simulation results. Finally, the characteristics of FPGA high speed, high stability is used to make the HDL module design of CIC filter under the environment of QUARTUS.
