计算机进行数据采集及数据处理的精度,主要取决于模一数(A/D)转换电路的分辩率和转换精度。A/D器件在转换过程中能否发挥出其最佳特性,往往又受到它前置电路的影响。所以说,选择合适的A/D转换电路是保证计算机采集数据准确的关键。 在八位微型计算机自动检测中,大多采用八位A/D转换电路ADC0809及ADC0801等。其特点是转换精度高,速度快,转
Computer data acquisition and data processing accuracy, mainly depends on the modulus (A / D) conversion circuit resolution and conversion accuracy. A / D devices in the conversion process can play its best features, often by its front-end circuitry. So, select the appropriate A / D converter circuit is to ensure the accuracy of the computer to collect data the key. In the eight micro-computer automatic detection, most of the eight-bit A / D converter ADC0809 and ADC0801 and so on. It is characterized by high conversion accuracy, speed, turn

这是我第一次参加《江西教育》编辑部组织的全省通讯员、作者培训班，所以我格外珍惜这次机会。经过为期四天的学习，我受益颇丰。 “什么是教育新闻？我们该如何采写教育新闻？”培训班上，有学员问道。《中国教育报》江西记者站徐光明站长告诉我们，写好教育新闻，要学会讲“三种话”。一是要善于“讲新话”，包括通过借鉴吸收说的“洋话”；二是要学会“讲土话”，突出地方特色，力求与众不同；三是要精通“讲行话”，突出行业
