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.

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%.
