Text Book

This quarter we ordered a custom version of our textbook which will be sold at the UCSD bookstore at a signfinicant discount. It should be in stock in time for the class:

The Analysis and Design of Linear Circuits, 7th Edition (UCSD Custom), R. E. Thomas, A. J. Rosa and G. J. Toussaint, Wiley 2012. ISBN 9781118516553

This custom version contains only a selection of chapters from the standard hardcover version of the book:

The Analysis and Design of Linear Circuits, 6th Edition, R. E. Thomas, A. J. Rosa and G. J. Toussaint, Wiley 2012. ISBN 978-1118065587

Of course you can buy the hardcover version or you may also choose to buy used earlier editions dating back to the 4th edition.

Homework will be assigned from the 7th Edition though. 7th Edition is on the Science and Engineering Library Reserves.
