Policies and Guidelines

  • This is a 2 credit-hours course. You are expected to spend a total of 6 hours per week for this course. This is not a pass/fail course.
  • The class has been divided into various sections. Please find out your weekly schedule from your program coordinator.
  • Each lab session can be completed in roughly 2.5-3 hours.
  • After your weekly lab performance, you should visit the course website and download the pre-lab exercises and handouts for the next lab. You are expected to read them thoroughly before coming to the next lab session. Plan to dedicate 2.5-3 hours per week on reading the handouts and solving pre-lab exercises.
  • If assigned, hand in the pre-lab exercises at the start of each experiment.
  • There will be 11 lab sessions in total, including a computer based tutorial session on circuit simulation. Your performance in these 11 sessions will count towards 50% of your final grade. Your ten best performances will be used to compute your grade. Lab 0 will only be an orientation session and will not be counted towards course grading.
  • PROJECT
    • A major requirement for this course is a group project. The project will carry a weight of 25% in the final grade.
    • A list of project ideas can be found here. You can also suggest your own project idea, with the permission of the instructor.
    • You will do this project in groups of three (all members must be from the same section). You can also choose a mentor from the list of laboratory staff, who can guide you during your project.
    • By November 10th, 2009, each group must submit a proposal for a project. Here you can find a template for the projects with detailed instructions on how to write the proposal. A sample proposal is found here. (For those who can use LaTeX, here is the Tex file for this template.)
    • You will be expected to design, test and fabricate a small electronic system, thus demonstrating your understanding of basic ideas of electrical and electronic engineering.
    • Soon after you submit your proposal, the lab will be opened for extended hours to let you work on your projects.
    • In the last week of the semester, there will be a project exhibition during which your projects will be graded and displayed.
  • Attendance in lab sessions in mandatory. Failure to attend the lab sessions may seriously affect your final grade.
  • Make use of the hands-on circuit simulation and circuit board manufacturing workshops to facilitate your laboratory exercises as well as to enhance your project.
