正弦波拟合法评价数据采集系统通道采集速率

Using Sinuous Curve-Fitting Method to Evaluate the Rate of Data Acquisition Systems

介绍了数据采集系统采集速率的一种简单实用的评价方法，即正弦波拟合评价法．讨论了评价过程的误差来源，以及减小其评价误差的几种对策;同时给出了评价过程的计算机仿真结果。

One simple and useful method to evaluate the sampling rate of data acquisition system is introduced in this paper. It is a sinuous-curve-fitting method. The sources of errors are discribed, and finally, some methods to decrease the uncertainty of evaluation results are discussed herewith.
