Teaching Digital Devices by using Virtual Instruments

Abstract- In recent years the approach to theoretical teaching and practical training of the undergraduate students in the electrical and electronic measurement courses has received great attention, because the fast development of advanced technologies requires continuously updating the way of teaching electrical and electronic measurements. As far as digital instruments are concerned, only a theoretical support is generally supplied. It is very important to deeply understand the operation of the basic digital instruments, the frequency meter and the dual-slope voltmeter. This task can be achieved by the approach suggested in this paper: indeed, an educational tool has been realized; it consists on flexible virtual instruments developed in the LabVIEW ™ environment. In this way, features and performances of the instruments can be carefully analysed by the students
