Principles of Electronics

I've used these labs with slight variations for a number of years, but there may still be a few bugs lurking. The pdf versions are easily viewed with a pdf plugin for netscape or with Acrobat Reader from Adobe. Questions or comments are welcome. © 1996-1999 L.R. Fortney

Caution: I've been told that the postscript files do not always print correctly, probably because they use the New Century Schoolbook font that is not common outside the Mac world. I'll try to correct this in the near future. The pdf files seem to work fine.

Each of my lab stations is equipped with a dual trace oscilloscope, a 0.1 Hz - 1MHz signal generator, and a Proto-Board PB-503 enhanced breadboard.
