The digital systems in microprocessors have significant importance in the area of
electronics. Adequate competency needs to be developed by giving sufficient practical
knowledge in microprocessors (programming as well as interfacing), A/D, D/A
Converters and other topics. Help may be taken in the form of charts, simulation packages
to develop clear concepts of the subject. Programming exercises other than the tested in
circulation may be given to the students.
