| 摘 要： | 本文讨论的是高速数据采集技术问题,其中重点阐明利用 CCD(电荷耦合器件)作为模拟一数字变换器(ADC)的中间暂存器,把高速变化信号采样后的信息按顺序快速输入 CCD 中暂存起来,供给低速的 ADC 变换,变成二进制数字量。这种利用 CCD 器件采用快入慢出(FISO)工作方式是解决高速模拟量变换成相应数字量的最新技术。它可以把 ADC 变换率提高到100MHz,而成本却提高很小。

| Abstract: | The problem of high-speed data acquisition is discussed in this paper.It is explained that CCD is taken as a temporary memory of ADC,the sample informations from the high-speed data acquisition are quickly stored in CCD one after another,and then are offered to the low- speed ADC converting into binary digit quantity.The method of fast in- put-slow output by the use of CCD is a new technique of converting high- speed analogical quantity into corresponding digital quantity.It can raise the converting speed of ADC up to 100 MHz,but the cost rises little. |
