| 摘 要： | CIC（cascaded integrator comb）滤波器的结构简单,需要的存储量小,是被证明在高速抽取和插值系统中非常有效的单元。它主要用于采样速率的抽取,同时具有低通滤波的作用。CIC滤波器的主要特点是,仅仅利用加法器、减法器和寄存器,因此占用资源少、实现简单且速度高。介绍了CIC滤波器的基本组成原理,并在此基础上,提出了滤波器的各项参数的选择和设计CIC滤波器的基本方法,用Verilog HDL语言在FPGA和MATLAB上分别进行了仿真,并且验证了设计的可靠性和可行性。

| Abstract: | CIC filter is a very effective unit in high-speed extraction and interpolation system,which has simple structure and the small needs of storage.It is used to decimate the sample frequency.and it is can be used as a low pass filter.The CIC filter is a flexible,multiplier-free filter which includes adders,subtracters and registers,so it uses less re-sources and can play well in high frequency.This paper describes the basic composition principles of CIC filter,Base on the theory of CIC filter,we have proposed ... |
