一个8031单片机控制的数字滤波系统

A Digital Filtering System Controled by a Single Chip Microcomputer 8031

本文提供一个设计IIR数字滤波器的实例,并用MCS—51汇编语言程序实现这个数字滤波器;介绍一个由A/D转换器、8031单片机和D/A转换器构成的实际信号处理系统;最后,对该系统进行试验。

The design of an IIR digital filter is described with an actual example and the digital filter is implemented by means of a MCS-51 assembly language program. The actual signal processing System which is Composed of an A / D Converter, a single chip microcomputer 8031 and a D /A converter is Presented. At last, the system is experimented.
