Summary

Electrical Engineering Uncoveredgives the reader an introduction to electrical engineering and a sense of what professional engineers do. The book uses familiar examples, like water flowing through a garden hose, to illustrate the electronics discussed and ease the reader into the subject.Topics include up-to-date Internet information; new material on micro-electro-mechanical systems (MEMS); digital electronics; computer architecture; communications; and digital signal processing. Short, one-page templates are included for the different kinds of technical writing an engineer would typically produce.As a reference for electrical engineers.

Author Biography

Eric Chaisson. Eric holds a doctorate in Astrophysics from Harvard University, where he spent ten years on the faculty of Arts and Sciences. For five years, Eric was a Senior Scientist and Director of Educational Programs at the Space Telescope Science Institute and Adjunct Professor of Physics at Johns Hopkins University. He then joined Tufts University, where he is now Professor of Physics, Professor of Education, and Director of the Wright Center for Innovative Science Education. He has, written nine books on astronomy, which have received such literary awards as he Phi Beta Kappa Prize, two American Institute of Physics Awards, and Harvard's Smith-Weld Prize for Literary Merit. He has published more than 100 scientific papers in professional journals, and has also received Harvard's Bok Prize for original contributions to astrophysics.

Steve McMillan. Steve holds a bachelor's and master's degree in Mathematics from Cambridge University and a doctorate in Astronomy from Harvard University. He held post-doctoral positions at the University of Illinois and Northwestern University, where he continued his research in theoretical astrophysics, star clusters, and numerical modeling. Steve is currently Distinguished Professor of Physics at Drexel University and a frequent visiting researcher at Princeton's Institute for Advanced Study and the University of Tokyo. He has published over 40 scientific papers in professional journals.
