摘要
采用TMS320F240数字处理芯片实现了一个陷波滤波器,主要利用其片内的A/D转换器、丰富的中断功能、定时功能、快速方便的指令和它的16位的乘法特性等,时频变换时采用了双线性变换法,给出了滤波主程序,此滤波器用于数据采集和处理模块中,效果很好,同时这种数字滤波的设计方法具有一定的通用性.
A digital notch filter based on a TMS320F240 digital signal processor was designed .This design is accessed through utilizing on-chip A/D,powerful interrupt hangling capacity,etc.Bilinear transforming was used in z transforming.This digital filter used in a data acquiring and disposing system is proved very good.
