摘要
比较了ＤＳＰ系统多通道数据采集的实现方法，分析了多通道数据采集的主要体系结构及其各自的优缺点，提出了一个高性能价格比的解决方案和在ＤＳＰ系统中应用ＡＤ７８７８实现多通道数据采集的方法，给出了一个应用ＡＤ７８７８实现单脉冲雷达差支路ＡＤ变换的实例，并进行了系统性能校验．
With an aim to compare the chief methods of realization of multi-channel data acquisition in digital data processing and to offer a high performance to priceratio, the characteristics of the main multi-channel data acquisition architectures are analyzed. The AD7878─an AD converter specified for DSP systems is introduced . A DSP data acquisition system consisting of the AD7878 is advanced, and its spstems performance testified through actual measurements.
