The design of virtual wave displayer based on LabVIEW
Abstract
Virtual instrument is the produce that merges the computer technology and measurement technique￡?It stands for a brand new development directory in the field of auto-measurement and electronic measurement?￡ With the rapid development of information technology and the computer technology, the digital signal processing takes an emerging discipline, its importance displays day by day in each domain application. This article introduces how to develop virtual instruments using graph programming language-LabVIEW ,designs a virtual signal displayer based on PC and explains the important part and wide development prospects of virtual instrument in modern measurement technique field￡? In a sense, ?°The software is an instrument?±.
