摘要
科学实验和实际生产中需要对各种模拟信号进行测量,然后进一步的分析或控制,信号数据和微处理器相互传送时必须通过模数转换,AD574是常用且精度较高的A/D转换器。根据AD574的工作特性,其转换后的数据并非实际值,需相应的程序进行数据处理。本文介绍了一种AD574模数转换后数据处理程序的设计方法,算法简洁,运行速度快,在模拟信号的数据采集中发挥了优势。
In the scientific experiment and practice of production, the analog signal often need to be converted to a digital signal. According to the features of AD574, the data converted are not the real value, and need to be processed with data processing program. This paper presents a data processing program used in AD574 for analog-digital converting. The idea of the design is simple and the running speed is high.
