基于80C196KC单片机PTS的交流采样技术

A AC Sample Method Based on 80C196KC Microprocessor Peripheral Transcation Server

提出一种基于８０Ｃ１９６ＫＣ单片机外设事务服务器ＰＴＳ的交流采样方法，能方便实现多路信号的采样，并采用频率跟踪技术来消除系统基波频率波动的影响。本方法可大大缩短Ａ／Ｄ转换时间，减少软件开销，从而提高 ＣＰＵ的事务处理能力。

This paper presents a AC sample method basbed on 80C196KC microprocessor's peripheral transaction server (PTS), which can conveniently sample multiple-channel singal,in additional,adopt frequency traching method to decrease effect of frequency change.This method can decrease A/D conivent time, decrease software expense,and improve CPU processing capability. In fact,this method has some practical value.
