本文介绍的是在IBM—PC微计算机上开发的一种模拟输入输出的功能卡(即通称的A/D—D/A接口卡)。将它直接插入主机的I/O扩展槽口中,就可以在机上实现控制、数据采集、信号处理等,在各个领域中应用。该接口卡的最大特点是转换速度快,精度高,使用操作编程简便,价格低廉。
This article describes an analog input and output function card (aka A / D-D / A interface card) developed on an IBM-PC microcomputer. It will be inserted directly into the host I / O expansion slot, you can control the machine, data acquisition, signal processing, etc., in various fields. The most prominent feature of the interface card conversion speed, high precision, easy to use programming, low prices.
