A Custom Printed Circuit Board Differential Amplifier For Instruction In Undergraduate Analog Electronics Kenneth J. Soda Department of Electrical Engineering United States Air Force AcademyAbstractInstruction in the theory and operation of analog electronic circuits remains an essentialelement of contemporary electrical engineering curricula. While computer basedsimulation of these circuits is extremely helpful to mastery of essential topics, hardwareimplementation of these circuits in the undergraduate electronics laboratory bestreinforces theoretical explanations and solidifies
of inherent interest to students. The specificapplication studied in this laboratory is the addition of small amounts of nitrogen to altermicrostructure in the weld deposit. Understanding the process requires the integrated use ofthermodynamics, kinetics, physics, chemistry, solidification, heat and mass transfer, phasestability and materials engineering.Few laboratory experiences allow engineers to explore the performance of real engineeringmaterials at homologous temperatures greater than 0.8. Fewer still enable students to relatematerial performance at these temperatures to the microstructure of the material. Moreover, therelationship of material properties at lower temperatures are rarely graphically and directlyconnected to the
processes areencountered in a large number of engineering applications. It is essential for thermal engineers tounderstand the principles of thermodynamics and heat transfer and be able to employ the rateequations that govern the amount of energy being transferred. However, the majority of studentsperceive these topics as difficult.To make the subject of heat transfer a more pleasant experience for the undergraduatemechanical engineering students at Indiana University-Purdue University Fort Wayne, thestudents are required to take a junior-level heat transfer laboratory. The different experiments inthis laboratory enhance and add another dimension to the teaching/learning process of thesubject of heat transfer. One of the objectives of this heat

Moderncomputation tools equipped with simulation and visual capability can ease explanation of topicsin vibration and control theories in the classroom and laboratory. Through the use of thesemodern visualization and simulation tools, it is possible to teach “mathematically advancedconcepts in vibration and control courses in engineering” more efficiently and make it moreinteresting for them to understand.This paper describes teaching vibration and automatic control courses in the Mechanical andElectrical Engineering departments at the West Virginia University Institute of Technology.Experiments are designed to give student thorough understanding of basic

The new project willlargely focus on the development of a few more key modules, the enhancement of several of theexisting modules with defined laboratory exercises and kits and a published digital media for usewith the modules. This paper will provide background on the first NSF project and describe thecurrent and pending accomplishments with the most recent project. Details will be presented onthe project’s modular approach to aerospace manufacturing education including: topic selection,module development, lab kit development, module implementation, and module dissemination.Current State of the Aerospace IndustryThe aerospace manufacturing industry continues to face a myriad of
presence of a prototype exemplar in an introductorydesign experience is described. The design experience occurred early in an Introduction toEngineering course following a single lecture on the engineering design process. The designactivity, necessarily simple at this stage, consisted of designing, building, and testing a dragracer, constructed from LEGO® MINDSTORMS® NXT parts and powered by a single rubberband. Students participating in the design experience were divided into two functional groups:laboratory sections where a prototype exemplar was present and laboratory sections were noexample was provided. Assessment of the prototype exemplar impact was accomplished througha two-pronged approach. First, photographs of each racer were taken at
systems and data structures. The courseis a lecture course with no accompanying laboratory, but since the board is relativelyinexpensive, a board was loaned to each student for the duration of the semester. So, studentshad full access to the board, and they wrote and tested DSP algorithms as homeworkassignments.The author wrote starter code that demonstrates a few real-time DSP algorithms (stereopassthrough, lowpass filter, highpass filter, and reverb) and serves as a starting point for thestudents when they write their own programs. The starter code includes several features thatmake working with the board more convenient such as a menu that makes it easy to switchbetween different algorithms and to select the input source (either line-in or the

Watt-Hours (energy monitoring) H. DemandThe data would be in the form of a printout that consisted of a list of data at a certaintime. The 808 could be programmed so that the data would be printed at certain fixedintervals. The paper tape printout can be thought of as the memory of the Dranetz 808.Having used these meters in the 1980’s, I can say that they were a real advance in powermeasuring techniques. However, they were difficult to use in a laboratory setting. Onedisadvantage that

engineering technology students are especially motivated by their real-timeprocessing learning experiences. To accommodate such a learning environment, our DSP coursewith laboratories has been improved, in which each lab concurrently requires MATLABsimulations as well as real-time processing coding with a digital signal processor such as TexasInstruments’ TMS320C6713 DSK.This DSP course is the second signal processing course in electrical and computer engineeringtechnology (ECET) program. The pre-requisite includes student working knowledge and skills ofLaplace transform, Fourier series, Fourier transform, and different types of analog active filterdesign. After completing the course, students not only become familiar with MATLAB softwaredevelopment

Also, the program is tailored toengineering research objectives that include elements of innovation and technology development,as opposed to discovery (in the natural sciences). Rather than spending extensive periods in aformal teaching laboratory, the students often spend time in the engineering makerspace and/or inthe research labs of their faculty mentors. Research projects are conducted in small teams,generally 2-4 students per team, and students are expected to spend approximately 5 hours/weekon their research—enough time to make steady progress on their project but not
