Traditional method for designing analog and digital systems is to use electronic equipments and kits, tailor-made for each specific application. This approach requires large working space and results in increase of inventory over the years. In the long run, the cost of equipping and upgrading the laboratory becomes quite expensive. However, with the availability of Personal Computers and design software at affordable prices, experiments are set up using these aids. Keeping abreast of the technology, our labs are now equipped with a network of computers with various software tools such as SPICE, ORCAD, etc. for development of both analog and digital systems. Practical and hardware aspects of the experiments are retained by interfacing standard add on cards or by cards specially built by the students for specific experiments.
