We propose in this paper an evaluation method for the transient performance of DAS,through the period signal, by utilizing the much smaller difference than sampling period between the multi-periods of signal and the multi-sampling periods,getting shorter

本文介绍一种方法，通过对其加载特定的周期性输入信号，使用采样周期的整数倍和信号周期整数倍间的微小偏差，获得比实际采样周期小得多的等效采样周期，从而解决了数据采集系统瞬态响应特性的获取问题；并进而获得了数据采集系统传递函数的辨识和评价结果，实现了数据采集系统瞬态特性的总体评价。
