单片机系统中模数转换精度探讨

SCM System Accuracy of Analog-Digital Conversion

在研究单片机的过程中，重要的环节是模数转换，特别是在以单片机或计算机为核心的系统中起着至关重要的作用。这篇文章主要介绍了用MCS-51单片机系统控制积分电路正、反向积分，通过简单计算，并得出实现N位模数转换。每次A/D转换时间为2s。

SCM in the study process,the important part is the analog-digital conversion, especially in the microcontroller or computer as the core of the system plays a vital role.This article describes the use of MCS-51 microcontroller control system integrator forward and reverse integration,through simple calculations, and draw to achieve N-bit analog-digital conversion.Each A / D conversion time of 2 N＋1 μs.
