LabVIEW is a complete computer language that can be used like Basic, FORTRAN, or C. In LabVIEW one creates virtual instruments that aesthetically look like real instruments but are controlled by sophisticated computer programs. There are several levels of data acquisition Vls that make it easy to control data flow, and many signal processing and analysis algorithms come with the software as premade Vls. In the classroom, the similarity between virtual and real instruments helps students understand how information is passed between the computer and attached instruments. The software may be used in the absence of hardware so that students can work at home as well as in the classroom. This article demonstrates how LabVIEW can be used to control data flow between computers and instruments, points out important features for signal processing and analysis, and shows how virtual instruments may be used in place of physical instrumentation. Applications of LabVIEW to the teaching laboratory are also discussed, and a plausible course outline is given. INTRODUCTION The development of powerful personal computers and workstations has transformed the way biophysicists and other scientists work. Increased processing speed and available memory have led to the development of highly sophisticated programs that perform intricate calculations and handle large data sets.Electronic signal processing can now often be replaced by digital computer processing. Windows and graphical user interfaces have made it possible for computers to perform multiple tasks simultaneously and have made it easier for scientists to analyze and display data as well as to write papers, manage references, and so on.Although compu
