Engineering Design Statement:

Laboratory projects are practical examples which may be solved by various design methods considering timing, power and economical issues. They require the students to perform designs of varying complexity using only a limited selection of components. Students use circuit breadboards to construct and test their designs employing oscilloscopes, digital voltmeters, and waveform generators. The descriptions in the laboratory sheets become less detailed as the course progresses, and the students’ designs are evaluated considering practical timing, power and loading requirements. Instructors base part of the grade on the quality of the final design. Additional design experience is gained by learning a CAD software tool as part of the laboratory requirements. Lab, test and homework questions might have non-unique solutions to stated objectives and require the use of design methodology.
