摘要
本文提出一种新的采样方法,称为异步采样法.对不同频率信号均采用固定采样周期,通过补偿,减小同步误差对测量准确度的影响.计算机模拟实验与理论分析结果相符.达到与准同步方法相当的测量准确度.
In this paper an asynchronous sampling method is proposed as a new method of measurement.The sampling period of this method is fixed for different wave frequencies.The synchronous error may be compensated by calculation.The results of the computer simulation agree with the theoretical analysis and reach the same accuracy as the quasisynchronous one.
