Physics 48 - Basic Electronics for Physicists
|Department of Physics and Astronomy, Dartmouth College
||Summer 2001 and 2002
Physics 48 is an introduction to electronics for students who have had
Physics 14 (or 16); in particular, second-year physics majors who are enrolled
in Physics 41 are encouraged to take this course. The course is designed for
students who wish to learn about analog and digital electronics.
The course begins with the fundamentals of linear lumped circuits using passive
components, including node and loop analysis, Thevenin's theorem, and impulse
and frequency response of AC circuits. Diodes, transistors, and operational
amplifiers are introduced, and active circuits involving feedback are
discussed. The basic components of digital electronics are introduced. Other
topics to be addressed include: tranmission lines, noise, stability, and
analog-to-digital conversion. A laboratory accompanies the course which allows
the student to gain practical experience in building and testing the circuits
discussed in lecture. An independent project is required in which the student
will become acquainted with computer-aided layout of a printed circuit board
Prerequisites: Physics 14 or 16, and Mathematics 23.
