摘要
研制了一种基于PC总线连接二极管阵列检测器与计算机的信号处理卡。其功能是通过放大器、滤波器、计数器和A／D转换器把二极管阵列检测器的模拟输出信号转换成16位的数字信号，供计算机采集。介绍了信号处理卡的硬件结构及其虚拟设备驱动程序的开发方法。
A signal processing card was designed for connecting diode array detector (DAD) of HPLC with computer through PC bus.The funetion of the card is to convert the output signal of DAD into 16 bits digital signal via an amplifier,a fliter, an arithme neterand an A D converter to be collected by PC. The framework of the card is described and the development of its virtual devicedriver(DxD) is discussed.
