10:00 –12:00 TR, and by appointments
Prerequisites: PHYS2140
Class Hours: 1:00-5:50 Tuesdays, Room MH2026
Grades given are the A, B, C, D, F including plus and minus. Grades are based on the
combination of the following six scores:
Laboratory designs and reports:
55%
Final Project:
15%
Midterm Exam:
15%
Final Exam:
15%
(Oral presentation of your project: 3-5 minutes per student. For assessment purpose)
The last day for withdrawing from the course without receiving a grade F is March 20. Class
attendance is mandatory to receive credits. Lab reports must be authored by individual
students, though sometimes a common set of data may be shared by the same group.
Course Description:
In this course, students are introduced to basic electronics that form a starting point to
measure physical quantities and to interface to computers for data acquisition, analysis, and
control. The emphasis is on the hardware side, while students are encouraged to engage in
software self learning to enhance the computer interface and control.
Instead of systematically learning electronics theories, this course will rather base on
modular introduction of commonly used electronics and theories associated with them to
emphasize the practical usages. Because of this, there is no required textbook for this course.
We will learn how to collect needed materials and information through internet and lay down
a good foundation of self learning. A good reference book is “The Art of Electronics” by
Paul Horowitz and Winfield Hill that gives you not only theories and applications, but also
advices of to-do and not-to-do that can only come with many years of real experiences in
electronics designs.
Advice:
Keep a good laboratory notes with neat schematics. Collect data sheets for references that
might be useful in the future. Learning electronics cannot be achieved with one semester
introductory course but a lifetime long hobby and devotion. Have a USB thumb drive around
you to copy and share free software to facilitate the exchange of ideas and designs. If you
would like to submit homework by email, everything has to be zipped before you send it.
