。介绍了内插器和抽取器这2种CIC滤波器各自的结构与性能，从数学上分析了其性能及其与FIR
滤波器的关系，从频域上展示了其本质。并讨论其内部寄存器的最小位宽与溢出保护，最后介绍了抽取器与内插器分
别在FPGA上的一般实现方法，并指出了一些提高实现性能的措施与建议-. Introduction of the interpolation and Extractor This two kinds of CIC filter structure and properties of their respective, from the mathematical analysis of its performance and its relationship with the FIR filter, from the frequency domain to display its essence. And to discuss its internal register with the smallest bit overflow protection, and finally introduce the Extractor and interpolator, respectively, in the FPGA to achieve the general methods, and pointed out that a number of measures to improve performance and recommendations
