| 摘 要： | 本文主要研究基于TI的DSP（Digital Signal Processor）芯片TMS320F2812的数据采集和数字滤波的实现。数据采集部分通过TMS320F2812芯片上自带的12位ADC（Analogto Digital Converter）实现对一路模拟信号数据的采集；数字滤波部分采用两种不同性质滤波算法对采集转换后的数字信号进行数字滤波处理，滤波结果以波形的形式显示出来，验证了该设计的正确性。

| Abstract: | This paper presents a data acquisition and filtering system based on the DSP TMS320F2812. The data acquisition part of this system is implemented by a 12-bit ADC（Analog to Digital Converter） which is integrated on the TMS320F2812 chip. Two different filtering algorithms are presented. The experimental results are also given. |
