| 摘 要： | 数据采集系统动态特性的辨识和评价，是其总体性能评价中至关重要的一个目标。本文通过选取几个相互比较独立的指标来总体描述数据采集系统的动态特性，然后通过几个特殊的模型化方法将其动态特性分别以动态有效位数、传递函数、阶跃响应曲线和幅频特性、相频特性的方式给出，从而解决了数据采集系统动态特性的总体评价问题。

| Abstract: | In the overall evaluation of data acquisition system(DAS),it is the most important aim to identify and evaluate the dynamic characteristics of DAS.Through selecting several relatively independent indexes,the dynamic characteristics of DAS has been presented overall in this paper.And then the dynamic characteristics given by methods of dynamic effective bits,transfer function,step response,and amplitude frequency and phase frequency characteristics respectively have been proposed by several special modelling methods.As a result,the overall evaluation of the dynamic characteristics of DAS has been solved. |
