摘要
CIC滤波器结构简单,不使用乘法器,计算效率高,并且具有系统稳定和线性相位,非常适用于通信系统中抽取前抗混叠滤波和插值后的平滑滤波。分析研究CIC滤波器基本结构和性能指标分析,给出了实际应用时的定点化设计方法及其异常处理机制。
CIC filter structure is simple;no multiplier;computational efficiency is high and has the system stability and linear phase;very suitable in communication system for anti-aliasing filter before extraction and smoothing filter after the interpolation.This article presents a practical application of the fixed point design method and exception handling mechanism through the CIC filter basic structure and performance analysis.
