摘要
Abstract
Aim It is described that the uncertainty of evaluation results of sampling rates of a linear measurement system by using the data number counting method in one standard signal periods, including the courses of analysis and evaluation of uncertainty of sampling rate. Some error sources of sampling rate evaluation are discussed, including the error of signal frequency, the length of sampling sequence, the number of signal periods in the whole sampling sequence. Methods Several main methods about decreasing the sampling rate evaluation errors and evaluation uncertainty have been proposed. Results In a group of examples of experiment, the analysis and evaluation results of sampling rate and its uncertainty by using the method in this paper is presented. Conclusion The courses and conclusion of analysis and evaluation of sampling rate uncertainty in this paper, can be applied to the uncertainty evaluation of measurement standards of relative specifications, can also be used in the uncertainty evaluation of sampling rate itself.关键词
