电子计数器测量周期的误差分析

Error Analysis of the Measurement Cycles of Electronic Counter

从电子计数器测量周期的原理出发,分析了测周误差产生的原因并指出测周误差由量化误差、时基误差、转换误差三部分组成,在此基础上提出了减小电子计数器测周误差的几种方法;为电子计数器在频率、时间间隔等参数测量时,如何减少测量误差提供了理论依据。

From the principle of measuring cycle of electronic counter, it has been found out that the error of measuring cycles consists of three parts, that is, quantization error, timebase error and conversion error. After these errors being analyzed, several methods of reducing error of measuring cycles have been put forth; which might serve as a theoretical basis for reducing errors when parametric measurings of frequency and time interval are involved.
