Virtual Instruments For Distance Learning

Using the sound card and CD player that are virtually a standard on the personal computer, LabVIEW virtual instrument programs have been developed that transform these instruments into a dual-channel virtual oscilloscope and a virtual function generator. With the addition of an inexpensive analog multi-meter, and some simple signal-conditioning circuits, these instruments can be calibrated and used in both analog and digital electronics laboratories to perform some of the laboratory exercises at the remote location. Using readily available networking software, the student can interact with their instructor for help in troubleshooting circuits, and to exchange the essential information needed to complete the laboratory at the remote site.
