摘要
CIC滤波器广泛应用于数字信号处理。CIC滤波器只需加法器便可完成滤波,结构简单,效率较高,并且可以减弱频谱的混叠效应。针对实际应用中要求对不同带宽信号进行处理,本文提出了抽取速率可编程的CIC滤波器设计方案,并针对不同速率时的截位问题进行分析。验证表明,本文提出的截位方案符合项目性能要求。
it has high processing, CIC Filter is widely used in digital signal processing. CIC filter has simple structure. It uses only adder so efficiency, and it can reduce spectrum alias. According to the requirement of different bandwidth signal this paper proposes a design scheme of the rate programmable CIC decimation filter, truncation of different rate. The simulation indicates the scheme meets the performance requirements and analysis the of the project.
