| Abstract: | The quickly development of Virtual Instrument makes the modular instrument,which is on computer control ,is accepted and applied widely.The meet between the LabWindows/CVI and MATLAB is build,so the mix-program betweenthe two software is realized,on this basis a data acquisition system and frequency-field signal processing system is presented.Through the technical combination of hardware and software,the signal acquisition and processing of various kinds of param-eters from multiple analog data are realized.In order to save the time of exploring the system and reduce the difficulties,themodular programming technology is used. |
