To:EE 1001 ClassFrom: Stan Burns27 September 2019Re:Upcoming Quiz 1 Secrets of the UniverseAs you know I have taught EE 1001 before. This document includes sample questions I have used on past quizzes that cover approximately some of the same topical areas. This should give you some idea as to my mindset on these topics. Several important points to note:Technology advances very quickly in EE, consequently technology-related questions and appropriate answers from past quizzes, even those from last year, could be different. Use your judgement after reviewing the WEB site presentations. Also departmental, college, and university personnel changes from year to year.Answers to any quiz questions must be based upon the latest information provided in the WEB posted information and during class presentations.Quiz 1 is scheduled for Monday, 7 October, and will cover topics through 2 October which is the Minnesota Power presentation by Andrew Remus.There are no sample questions posted for Power Electronics, 25 September, by Prof. Fang; however, you are also responsible for that material.Because of the way the schedule changes from course offering, some of the sample questions may include questions related to topics and speakers. Obviously, questions related to topics and speakers not yet introduced would not be covered on this Quiz 1. These should be recognizable as you go through this review guide.This review is not meant to be comprehensive, only a sample of what has been asked on previous quizzes covering similar topics. These sample questions provide insight into my brain about what is important.If you are a freshman or sophomore as of Fall Semester 2019 credit count, you are to form a two-person team to take the quiz. You should identify your “study buddy” partner in advance. Both of you will earn the same grade in this two-person team effort. It is important to realize that most engineering efforts requires teamwork and this is one way I can demonstrate this in an academic setting. This teaming approach is often called the “flipped classroom” and active learning pedagogy. If you do not arrange your team in advance, I will match you up when you come to class with the chance you may have to take the quiz individually.I recognize that everyone has different learning styles. If you choose to take the quiz individually, please let me know one day in advance so that I may prepare enough copies.If you are a junior or senior as of Fall Semester 2019 credit count, you are not to team up with a freshman or sophomore; you may also must take the quiz individually or team up with another junior or senior. Quiz 1 Ground Rules.Open notes and laptop/tablet/smartphone, WEB is OK but watch your time management when you surf the WEB. Not a good use of time to watch cat videos during the quiz! ? No communications between teams using WiFi, IR links, wireless, IM, Bluetooth, texting, social media etc.After looking at the syllabus through 2 October, I can identify four key topical areas:Your EE Department Faculty and Student OrganizationsDigital Circuits and Systems including binary, decimal, and hexadecimal conversions. Boolean algebra.Power and Energy and Power ElectronicsCirrus, Boston Scientific, and Minnesota Power industrial presentationsFeel free to stop in my office if you have any questions or need assistance on these sample questions but please do not wait until the last minute!Your textbook are the Powerpoints on the EE 1001 class WEB page.What Boolean function is realized by each of the three truth tables?
