多级CIC滤波器的FPGA实现

摘要

CIC filter was a high efficiency filter, widely used in digital down conversion end software radio. It introduces the basic principles of CIC decimation filter and filter Hogenauer structure. Using Verilog HDL language programming to achieve this filter through MATLAB and Modelsim co-simulation, synthesis verify the correctness of the design and feasibility.%CIC滤波器是一种高效的滤波器，广泛应用于软件无线电的数字上下变频端。介绍了CIC抽取滤波器基本原理及其滤波器的Hogenauer结构。用Verilog HDL语言编写程序，实现该滤波器，通过MATLAB和Modelsim联合仿真，综合验证了设计的正确性和可行性。
