Meeting Times
Class: Tuesday and Thursday, 9:30-10:50 a.m., Carnegie 204

Lab: Meets in Carnegie 328

Text/Materials
The text is Physics of Hi-Fi: Analog to Digital, by Orest Symko. This book is recently out of print, awaiting a new edition, but we have acquired permission to use photocopies. You need a laboratory notebook - an 8 ½" x 11 " spiral bound notebook is suggested. Bring a calculator to class and to lab.

College Course Catalog Description
Physics 104. Physics of Electronic Sound. An introduction to electromagnetism and electronics through the analysis of high-fidelity sound recording and reproduction, and room acoustics. Demonstrations and laboratory exercises are integrated with class work.

Class
Class attendance is essential to success in this course. I supplement the reading with demonstrations, videos, listening exercises and computer simulations. These will be difficult to experience fully through a friend's notes. On the syllabus, the reading assignment for a given day will be discussed in class that day. I encourage you to read the text before class, and bring in questions that arise. On most thursdays you work in groups on problems that are handed in at the end of class. These will contribute to your final grade. On tuesdays I introduce the laboratory for that week, while on thursdays time is reserved for discussion of the lab write-up. Always ask questions!

Office Hours
Monday, Tuesday, Thursday 11 a.m., or by appointment. Don't hesitate to stop by at other times, I can usually break free from what I'm doing to discuss course-related topics. To set up a specific appointment, either call me at x6323 or send an e-mail .

Problem Assignments
At the end of each chapter in the text, there are two sections called Questions for Review and Exercises. I provide solutions to these on the course web page. After reading a given chapter, you should work through as many of these as  you can before using my solutions as a guide. I'm happy to talk about any of the solutions during class. The in-class problems on thursdays will be most representative of the types of questions I ask on exams. Solutions to these problems will be posted on the web page as we work through them during the semester.

Laboratory
Experimental work is an essential component of physics and of attempts to understand nature. You are required to complete all laboratory experiments, during your regularly scheduled lab section,  in order to pass the course. In the event of a medical situation or family emergency, you may seek authorization from the Dean of Students and contact me to arrange make-up of a missed lab, otherwise, come to the assigned lab section on time. All your lab notes, measurements, analysis and conclusions are kept in your lab notebook. Experiments are done on tuesdays and wednesdays, and laboratory notebooks must be handed in by Friday at noon sharp. Notebooks are graded and returned at the beginning of your next lab session. Detailed lab notebook tips are available on the web page.

The Project
You may work either in a small group of 2-3 or individually on a project. The last three lab periods of the semester are designated as project time. Some previous project activities include acoustical analysis of rooms on campus, design of a concert hall and speaker building. We'll discuss project ideas several times during the semester as the course evolves, and specific project guidelines are provided on the web.

Grading
Final grades will be determined according to the following weighting scheme:
