ENGR-4220 Electronics and Instrumentation

Background

• Dynamic Systems is the only listed prerequisite for this course.
• We also use concepts from most required math courses, physics courses, and basic engineering courses.

Class Materials

There is no standard text for this course. We will be using some readily available pamphlets and a lot of web-based info.
• Electronics class notes prepared by D.M. Gingrich of the University of Alberta Physics Department. These notes are sufficiently complete that they can serve as a textbook. Engineer's Mini Notebook Series by Forest M. Mims, available from Radioshack. We will be using the general formula book, the op-amp book, and the sensor book. A bound copy of the notes and copies of the 3 Mims Mini-Notebooks are available for purchase from Audrey Hayner in JEC 6003. The cost is $10 for all four.
• All students are required to purchase a kit consisting of electronic components, a protoboard, some tools and a storage box. These kits will be available soon (probably during the second week of class) for a cost of $40. Thus, the combination of the notes, notebooks, and the kit is still less than many textbooks. This kit was something new last term, but it significantly helped keep things running smoothly in the classroom and there are faculty teaching several other courses interested in doing something similar. It is likely, therefore, that you will be able to use this kit in a future course. Please check out the parts list to be sure your kit is complete when you receive it.
• There is an outstanding book on the practical use of electronics that we recommend as an additional reference. The Art of Electronics by Horowitz and Hill.

• Quizzes/Exams (40% of total course grade)
  • Practical Quizzes (2% each) -- To successfully apply the materials studied in this course, it is necessary for students to master a small number of practical skills. These include, but are not limited to, PSpice simulation, function generator and scope operation, protoboarding passive components, determining resonant frequencies, identifying logic gates, ... Several short (about one half hour) quizzes are posted below that address such practical skills. Two quizzes must be completed by the 8th week of class, two more by the 12th week and one more by the last day of class for a total of 5 quizzes to be completed by each student. Quizzes, which will be taken individually (no partners), can be worked on during open shop hours. Additional quizzes may be added later in the semester. Please read the quizzes over and discuss them with anyone you wish before going to open shop. Essentially no help will be available during the time the quizzes are taken. Only questions regarding such issues as terminology and equipment malfunction will be answered by the staff person in attendance. When the quiz is complete, it will be checked for correctness and signed off. Should the answers not be correct, some feedback will be provided regarding what is in error. Each quiz can be attempted three times without any penalty. However, for four or more tries, only partial credit will be given at the discretion of the grader. During the three semesters these quizzes have been given, over 99% of the grades have been for full credit.
    Practical Quizzes: Quiz #1, Quiz #2, Quiz #3, Quiz 4, Quiz 5, Quiz 6 and Quiz 7.
  • 4 Topical Quizzes (7.5% each) -- There will be one quiz on each of the main topics of the course, except for Instrumentation Methodology, which will be addressed in the practical quizzes. All Quizzes will be closed book, but students are permitted to bring one 8.5" x 11" crib sheet. Specific topics to be addressed on each quiz will be announced at least one week before the quiz date. Check the syllabus for last semester to see the kind of questions you can expect to see on the quizzes.
  • Optional Final Exam (Variable %) -- Students who wish to improve on their quiz grades will have the option of taking a final exam. Students who miss a quiz for ANY reason or who fail to complete all the assignments in the course will be required to take this exam. Details will be provided near the end of the term.
• Homework (10%) -- Assignments are made in class. Problems will be posted on the webpage or on the bulletin board outside the studio. Each student must hand in the homework.
• Experiments (20%) -- When an experiment is completed, the Experiment Completion Sheet must be signed by one of the TAs or the Instructor. All collaborating partners must be in attendance to obtain this signature. For full credit,the results, discussion and any calculations called for are to be turned in on the date announced in class. This date will also be posted next to the assignment schedule below.. Usually, this section can be completed as the experiments are being done. Thus, it will be best to hand in this sheet at the time the experiment is completed. Experiments are to be done by each pair of partners (2 students). Experimental data are to be shared by the cooperating partners (4 students). If the Experiment report is not handed in by the posted date, it can be handed in anytime before the following project report deadline for half credit.
• 4 Design Projects (20%)
  • Pre-Project Reports (10%) -- The general issues to be addressed in each report include the following:
    • Introduction (1 pt): Introduce and describe the goals of the project.
    • Design (4 pts): Describe your project design, how it works, how you came up with this particular design, and discuss potential problems. This last item is very important. You should not expect your initial design to be a complete success. Remember that you will have the opportunity to make changes while you build and test your project.
    • Analysis (3 pts): Discuss why your project should work and support your discussion with calculations, graphs, PSpice simulations, and common sense reasoning.
    • Personal Responsibilities (1 pt): A short paragraph should be written describing what each group member contributed to the project design.
    • Appendix (1 pt): Include any background materials you used in the preparation of your design.
    A list of specific issues to be addressed for each project will also be posted in the class announcements. A discussion of how your design deals with each of these issues must also be included at the appropriate place in your report.
  • Project Reports (10%) -- Your project report will describe how you implemented your designs, how well they worked, what changes you made and simulations, data, and calculations supporting your new designs, if any changes were made. All reports should include the following sections:
    • Introduction (2 pts) -- Problem statement and what was learned from this project.
    • Implementation (3 pts) -- Discuss what problems were encountered during the implementation of your project and how you solved them. Include advice you would offer to someone who wished to avoid these problems in the future.
    • Final Design (4 pts)-- Describe your final design, what needed to be changed and why. Show that the new design works with experimental data from your hardware and PSpice simulations. Include your PSpice schematics. Have your experimental data signed by a TA or instructor.
    • Personal Responsibilities (1 pt) -- A short paragraph should be written describing what each group member did to develop and implement the final design.
  • Late Penalty -- The Design Project Proposals and Final Reports are due on the dates indicated below. If they are handed in late, the following penalty will be applied. For each school day late (weekends and vacations are not counted): 1 point per day for the first two days, 2 points per day for the next three days, 3 points per day for the next four days, and so forth. Thus, if the pre-project proposal is handed in 5 days late, the penalty is 8 points. Please note that there are, at most, 5 school days per week.
• Participation (10%)-- A participation grade will be assigned for each of the experiments and projects, based on attendance and contribution to the classwork involved in each activity. You will earn 0.5% of your overall course grade for each experiment and 1% for each project if you are in attendance and doing your share. It will be possible to make up class time missed during open shop.
