摘要: 分析了数字滤波器不能彻底滤除高次谐波的原因,提出采用MAXIM公司有源滤波专用芯片MAX274 275作为前置滤波器来改善滤波效果,并对该芯片及其设计方法作了详细介绍.

关键词: 数字滤波; 窗函数; 有源滤波; 谐波;

Abstract: This paper analyses the reason why digital filter can not filter out higher harmonic completely and puts forward MAX274/275 as preposition filter and introduces it in detail.
