摘　　要：介绍利用软件同步采样实现周期信号分析的几种常用算法 ,通过仿真计算和比较 ,对常规采样法、偏差累积增量法和双速率同步采样法的误差进行了定量分析 ,为周期信号的测量选择提供了依据。This article introduces some algorithms for analyzing the periodic signal by software synchronization sampling, including the general sampling、cumulated deviation increment sampling and two speed synchronization sampling. Through emulative calculating and comparing, it analyses the error caused by each algorithm and provides some suggestions for how to select the right algorithm to periodic signal measure.
