Course DescriptionExplores basic digital electronics concepts. Includes number systems, Boolean algebra, logic simplification, and circuit troubleshooting. Includes analysis of digital logic using digital circuit simulations and basic spreadsheet skills. Audit available.
Addendum to Course Description
In the laboratory, the student will construct several digital circuits including a circuit that could be used to control a furnace and a circuit that lights LEDs in a specified sequence. The student will use standard laboratory instrumentation, including the oscilloscope, to verify the operation of each circuit. The student will also use PC-based electronic circuit simulation software to simulate the operation of at least one digital circuit.
Intended Outcomes for the course
Upon successful completion students should be able to:
1. Use basic electrical digital systems concepts and theorems to analyze circuits
2. Build and simulate electrical digital systems circuits and perform measurements with electronic test equipment.
3. Write technical reports using collected experiment data.
Outcome Assessment Strategies
Assessment methods are to be determined by the instructor. Typically, in-class quizzes, exams and weekly homework assignments will be used. Laboratory assessment will be by reports and/or practical skills testing.
