Course Description:  Physics 242 presents a one-course introduction to electronics, including some circuit theory, analog electronics, and digital electronics.  Experimental physicists often need to design and construct electronic circuits to acquire data from an experiment or interface to a computer, and all scientists and engineers can benefit from a better understanding of the capabilities and limitations of the electronic instrumentation they use.  Electronics is a fascinating area, incorporating interesting ideas at different levels, from semiconductor physics to the mathematics of circuit theory to the programming of microcontrollers.  Electronics is not just a challenging academic subject, though: it is also a fun hobby for many.  Don’t expect to learn everything in one course (despite the surprising heft of the textbook)—electronics is a large field!—but hopefully you will get a fun and challenging introduction to the subject.

Class Meetings:  MTuThF 2nd period, SMC D213 or SMC D103 (lab).  Labs will take place during the regular course meeting times; additionally, students are allowed access to the labs anytime to finish a lab or work on projects.

Instructor
: Tom Moses, D116 SMC, tel: -7341, email: tmoses@knox.edu.  You are encouraged to see me for help or hints with the homework problems or labs anytime you can find me in the physics wing.

Course Text
: Principles and Applications of Electrical Engineering, 7thed., Giorgio Rizzoni (McGraw-Hill, NY, 2021), ISBN: 978-1260258042.

Homework
:  Problems sets are available online at https://physics.knox.edu/OnlineHW/phys242/winter/.  As usual, completing the homework problems and reading the text is important for keeping up with the class.  You are encouraged to work together on homework problems, but the final write-up you turn in must be your own unique product.

Labs
:  Electronics is a lab subject, and we’ll spend lots of our time in the lab building and testing circuits.  Short lab write-ups (or occasionally, a demonstration of circuit functioning to the instructor) will be required.  Lab partners may share data and discuss the lab reports, but each student must submit his or her unique individual report.

Attendance Policy:  Attendance is required, and moreover good attendance is one of the best predictors of success in the class.  Excused absences will be granted for illness or quarantine, participation in college sporting events, previously arranged misses, and one free absence.  Each unexcused absences will result in a 0.5% deduction from your average.

Late Policy:  Like most science courses, Physics 242 covers ground at a rapid rate and you are strongly advised not to fall behind.  Please contact the instructor as early as possible if you need help.  Extensions can be arranged in case of illness, emergencies, and travel (but not due to deadlines in other classes)--contact the instructor in advance when possible.  Late homework and late labs are penalized 20%.
