Design of data acquisition and signal processing system based on LabVIEW

Liu Wufa

Abstract

It set up a virtual instrumentation with the function of data acquisition and signal processing,based on computer and PCI-MIO-16E-4 data acquisition card and software of LabVIEW8.20. The virtual instrument technology,the signal processing technology were adopted.The system includes the signal acquisition which can realize the data acquisition with single channel or two channel as well as signal generation and signal processing,and the software design of different parts of the analyzer was also introduced in detail.
