Homework Assignments: There will be approximately 10 homeworks. You are encouraged to collaborate with others in the course, but you should hand in only your own work. No late homework will be accepted (however, your lowest homework score will be dropped). Dates will be clearly identified on Gradescope, where all assignments will be assigned, submitted, and graded. If the homework is LaTeX’d, it will get extra points.
Labs: The labs are managed by Dr. Daniel Block and Lab TAs. The information on lab sessions (lab handouts and other details) are at http://coecsl.ece.illinois.edu/me340/. The labs are scheduled as follows.
|Sept 12||Lab #1|
|Sept 26||Lab #2|
|Oct 3||Lab #3|
|Oct 10||Lab #4|
|Oct 24||Lab #5|
|Nov 7||Lab #6|
|Nov 28||Lab #7|
- Lab attendance is compulsory and a passing grade for each of the seven laboratories is expected in this course.
- You must complete the pre-lab assignment and become familiar with that week’s lab handout material before arriving to lab.
- For all lab-related questions should be addressed to the lab TA assigned to your lab section.
- Make use of the lab office hours.
Examinations: There will be in-class quizzes and midterm exams and a final exam of 2 hours. Formats/dates TBA.
- Conflict Exams: Requests for a conflict or make-up examination will be individually evaluated. It requires a serious university approved documentation and are (almost) never granted. Please plan accordingly.
Extra Credit: You can earn an extra credit (EC) up to 5%. EC TBA.
|Homework assignments||45%||Approximately 10 HWs|
|Final Exam||20%||Time: TBA|
Grading Scheme: The total percentage \(p\) correspnds to final grades as follows
- A, if \(p \in\) [92%, 105%],
- B, if \(p \in\) [80%, 92%),
- C, if \(p \in\) [70%, 80%),
- D, if \(p \in\) [60%, 70%), and
- F, if \(p \in\) [0%, 60%).
- Please show respect for your classmates by limiting distractive behavior. You may use a smart phone, labtop or tablet to take notes or for other academic purposes directly related to the class. Mute your cell phones and other devices, and please keep any side discussions short and quiet.
- You are expected to adhere to all of the rules pertaining to academic integrity outlined in the UIUC Student Code (http://www.admin.uiuc.edu/policy/code/). Failure to do so will result in an automatic F for the course and a recommendation for removal from the University.

Special Accommodations: If you have any condition, such as a physical or learning disability, which will make it difficult for you to carry out the work as it has been outlined or which will require special accommodations, please notify the instructor during the first week of the course with the appropriate written documentation. To contact the Division of Rehabilitation-Education Services (DRES), you may visit 1207 S. Oak St., Champaign, IL 61820, call (217) 333-1970, or email firstname.lastname@example.org.
RHF Resources: Emergencies can happen anywhere and at any time. It is important that we take a minute to prepare for a situation in which our safety or even our lives could depend on our ability to react quickly. When we’re faced with almost any kind of emergency – like severe weather or if someone is trying to hurt you – we have three options: Run, hide or fight.
Emergencies can happen anywhere and at any time, so it’s important that we take a minute to prepare for a situation in which our safety could depend on our ability to react quickly. Take a moment to learn the different ways to leave this building. If there’s ever a fire alarm or something like that, you’ll know how to get out and you’ll be able to help others get out. Next, figure out the best place to go in case of severe weather – we’ll need to go to a low-level in the middle of the building, away from windows. And finally, if there’s ever someone trying to hurt us, our best option is to run out of the building. If we cannot do that safely, we’ll want to hide somewhere we can’t be seen, and we’ll have to lock or barricade the door if possible and be as quiet as we can. We will not leave that safe area until we get an Illini-Alert confirming that it’s safe to do so. If we can’t run or hide, we’ll fight back with whatever we can get our hands on. If you want to better prepare yourself for any of these situations, visit police.illinois.edu/safe. Remember you can sign up for emergency text messages at emergency.illinois.edu.
