摘要
本文介绍一种基于虚拟仪器的数字相位差计设计。该设计主要是labView开发平台下,用软件的方法来实现相位差的测量。它在过零检测法的基础上,用软件的方法对测量中的误差进行处理,提高了测量精度。该方法设计炅活、简单、实用。
This paper introduces a method for measuring digital phase difference based on virtual instrument. This design aims to measure phase difference by software method in the platform-labview. It bases on zero-crossing method and deal with the error in measurement by software method. It improved the precision of measurement. This method is designed flexibly, simply, practically.
