An electronic version of this text (including Mastering Engineering) has been preloaded in your D2L account. The cost will be billed to your Bursar account. More information is available by clicking here.
PHONES: Mobile phones must remain turned off and put away during class. The same applies for laptops and tablets.
HOMEWORK: Homework will be assigned and graded. See the Assignments page on the course website.
LABORATORY: One week before each lab you will complete a Prelab assignment, including exercises using the circuit simulation software PSpice. During each lab, you will build electronic circuits and take measurement data. A written Lab report is then required. You must complete the prelab before you will be allowed to attempt the lab experiments. You must complete all Prelab assignments and all Lab reports to receive any lab credit for the course. The Prelab and Lab assignments can be found on the Assignments page of the course website.
EXAMINATIONS: There will be four midterm examinations and a comprehensive final exam. Exam dates, topics, and rules are posted on the Exams page of the course website.
GRADING: See the Grades page on the course website.
ACADEMIC INTEGRITY: The Code of Academic Integrity (on the web at http://deanofstudents.arizona.edu/academicintegrity) is based on the guiding principle that a student's submitted work must be the student's own. In ECE 220, this policy will be applied to all work submitted for a grade, including exams, quizzes, homework, prelabs and lab assignments. Copying previously posted solutions or solution manuals is strictly forbidden. All work must be original. Sharing all or parts of PSpice programs and lab data/reports is strictly forbidden.
STUDY GROUPS: Discussing homework assignments in study groups can often be an aid to learning. However, as stated above, all work submitted for a grade must be the student's own. Students are encouraged to work through practice exams on their own, for obvious reasons.
WITHDRAWALS: Please check the UofA webpages for the deadline to drop the class without the permission of the instructor. If you drop by this date, no record will appear on your transcripts. After that, there is a second date up until you may withdraw from the class with a grade of W or E. The grade of W will be given freely until the Thursday following the first exam. After that, the grade of W will be given only if you are passing the course at the time. Note that students wishing to drop the course AT ANY TIME must take appropriate action. Ceasing attendance does not automatically drop you from the course. IF YOU ARE STILL ON THE CLASS ROLL AT THE END OF THE SEMESTER, YOU WILL RECEIVE 0'S FOR ANY WORK NOT COMPLETED AND WILL BE GRADED ACCORDINGLY.
ACCESSIBILITY AND ACCOMMODATIONS: At the University of Arizona, we strive to make learning experiences as accessible as possible. If you anticipate or experience barriers based on disability or pregnancy, please contact the Disability Resource Center (520-621-3268, https://drc.arizona.edu/) to establish reasonable accommodations.
THREATENING BEHAVIOR: The University has adopted the following policy on threatening behavior: http://policy.arizona.edu/education-and-student-affairs/threatening-behavior-students.
NONDISCRIMINATION AND ANTI-HARASSMENT: The University has adopted the following policy on Nondiscrimination and anti-harassment policy: http://policy.arizona.edu/human-resources/nondiscrimination-and-anti-harassment-policy.

COURSE OBJECTIVES: ECE 220 is the first circuits course required by all electrical and computer engineering majors. The course introduces the fundamentals of DC and AC circuits, and directly addresses the first of four ECE Educational Objectives, namely: to provide a first-rate education in the principles of analog circuits... (with) the use of hardware and software tools.
