An introduction to the basic principles of circuit theories, RL and RC circuits, transduction principles, mechanical measurements, instrumentation techniques, operational amplifiers, data acquisition, Programmable Logic Control, power electronics and electric machines and control.

Almost all mechanical systems incorporate electrical, electronic, and computational elements in the form of sensors, data acquisition units, signal conditioning and processing, control systems, motors etc. To use these elements effectively, Mechanical Engineers must have an understanding of how they work, their performance characteristics, and limitations. This course covers the fundamental electrical and electronic theories necessary to understand what is going on inside these elements, as well as practical aspects such as how their behaviour might affect their intended use in engineering applications.

The course complements Controls and Vibrations (ENME303) and serves as a foundation for subsequent elective courses in Instrumentation and Sensors (ENME423), Robotics (ENME413), and Linear Systems Control (ENME403), as well as Final Year Research Projects requiring instrumentation, data acquisition and processing.

This course includes 5 laboratory sessions during term 2. The labs are conducted on Programmable Logic Controllers (PLCs) with a variety of common sensors and actuators, giving students practical experience with industry standard equipment.
