基于相关原理的相位差测量及虚拟相位差计的设计

The Measure of Phase Difference and the Design of Virtual Phase Meter Based on Correlation Principle

本文根据相关函数的特性,通过自相关和互相关原理导出适合于虚拟仪器测量的数学表达式,由此设计出虚拟相位计,体现虚拟仪器中软件即仪器的观点.

This papers bases on properties of related function,devises out the suitable expresses for virtual instruments according to principle of AutoCorrelation and CrossCorrelation,then devises out virtual phase meter and embody that the software is the instrument.
