Electronics for Scientists

Physics 375

Spring 2008

Text: All the textual material can be found on the world-wide-web. I strongly suggest that you download as much of the material as you can, just in case the web has technical difficulties when you need material. The necessary web sites are

Hyperphysics

Electronic Circuit Theory

Electronics-Tutorials

All About Circuits

Lab Manual

The first three sources are a set of web pages to specific topics. The last link is to an online textbook. It is quite thorough but has one major flaw that we will discuss on the first day of class. I recommend against printing the entire lab manual at the beginning of the semester, as it will be revised throughout the term.

Course Objective: When you complete this course, you should be able to do simple circuit analysis, troubleshoot circuits, and design some simple circuits that are useful in the laboratory.

Grading: The grade that you earn in this course is determined by a combination of tests, homework, and classroom (laboratory) performance. There will be three tests. They will make up approximately 70 % of your grade. Homework and laboratory work will make up approximately 30% of your grade. Finally, your in class performance can affect your grade. This is a subjective determination and should be kept at a minimum. It can be very important if a student has a single bad test, for example. The grading scale is >85% = A, >70% = B, >60% = C, >50% = D.

Homework: Homework problems will be assigned throughout the semester.

Laboratory Work: Laboratory work will consist of experimental labs completed in room 217. Reports of results obtained from the laboratory exercises should contain the data in a reasonable format and answers to questions. Any additional observations are encouraged and expected when appropriate. Always use word processors, graphics packages, and printers capable of the quality available in 307C Moulton Hall.  Data tables should be done on a computer for ease of reading and as practice for data presentations. Graphs should be done with graphics software. When preparing a graph or analyzing a data set do not assume the data is linear. This is a sure way to lose half of the credit for the report. Check with the instructor if you need some advice (you have already paid for it).  Do not rely on sources that do not make policy.  Be sure not to use linear fits to data unless appropriate.  Spline fits and other numerical fits to data that do not originate from a theoretical prediction about your experimental results should be avoided as they are usually inappropriate. While you will work with a partner in the laboratory, you are expected analyze your data and prepare your report independently of your partner. Reports are due at 9:00 am on the first class day after finishing a laboratory experiment.  As a general rule, avoid simple spreadsheet programs for graphs.

Attendance: Your attendance is expected and required at all class times and laboratory times. See the instructor for exceptions.

Prerequisites: Physics 109 or 111 are prerequisites for this course. You will find the course extremely challenging if you have not had additional physics or math courses (Phy 217 and Mat 147, for example).

Course Outline: The following is a tentative list of material to be covered, homework problems, and laboratory exercises.  The topics are correct, but the chapters and problems will be adjusted once the book has been finalized.
