目前随着计算技术的迅猛发展,微处理机的作用正在我国开始初露锋芒。开展微处理机的应用工作,这是我国技术改造的一个有效途径。解决模/数及数/模转换问题是应用微处理机中所遇到的关键问题之一。本文主要想介绍具有新 S-100总线高分辨率的模/数及数/模转换板。所谓新 S-100总线就是指符合 IEEE-696标准的总线接口。目前大多数单位所具有的微处理机系统中,虽然有的单位也有模/数或数/模转换板但一般分辨率不高,大多数是8位。这里介绍的一种是具有12位分辨率的模/数及数/模转换板,这些转换板是美国 DUALSYSTEMS CONTROL CORPORATION产品。
At present, with the rapid development of computing technology, the role of microprocessors is beginning to emerge in our country. Microprocessor applications, which is an effective way to technological transformation in China. Solving A / D and D / A conversion problems is one of the key issues encountered in the application of microprocessors. This article mainly wanted to introduce the new S-100 bus with high resolution A / D and D / A converter boards. The so-called new S-100 bus refers to the IEEE-696 standard bus interface. At present, most of the units have a microprocessor system, although some units also have A / D or D / A conversion board but the general resolution is not high, most of them are 8 bits. Here is a description of the 12-bit resolution of the A / D and D / A converter board, the conversion board is the United States DUALSYSTEMS CONTROL CORPORATION products.
