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, 8th Edition (UCSD Custom), R. E. Thomas, A. J. Rosa and G. J. Toussaint, Wiley 2016. ISBN 9781119319894

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

The Analysis and Design of Linear Circuits, 8th Edition, R. E. Thomas, A. J. Rosa and G. J. Toussaint, Wiley 2016. ISBN 978-1-119-23538-5

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 8th Edition though. 8th Edition is on the Science and Engineering Library Reserves.

Grades Formula

GRADE = MAX(0.2 * HOMEWORK + 0.2 * MIDTERM1 + 0.2 * MIDTERM2 + 0.4 * FINAL,   FINAL)

Exams

• Midterm: Thursday, October, 24th.
  Exam and solutions.
• Midterm: Tuesday, November, 19th.
  Exam and solutions.
• Final exam: Wednesday, December, 11th, 11:30-14:29

Homework

• Homework, instructions and solutions will be posted on canvas.
• Homework will be posted every week, due the same week.
• This class uses an all-electronic homework submission and grading process.
• You can type and scan your homework for submission.
• No paper submissions will be accepted.
• Turn in every Friday at 23:59, every week.
• No late homework submissions will be accepted
• Please turn in a readable and organized homework. This is a big class!

Homework grading policy

• No points will be deducted by mistakes you make on homework.
• You will be assigned total points for every question you attempt to solve.
• A valid attempt has to show enough effort to convince the graders that you spent time on the question!
• Just repeating the problem statement IS NOT an example of a valid attempt.
• You get no points on a question if you did not attempt the question.
• Questions will be graded and feedback will be provided by the graders in case you make mistakes.

Homework #1

T R & T: 1.4, 1.9, 1.20, 1.22, 1.29, 2.7, 2.11, 2.15, 2.16, 2.27
Due: 10/04/2019

Due: 10/25/2019
IMPORTANT: You do not need to do any of the simulation using Multisim. There are some free simulators out there which you might want to try. However, simulations will not be required nor graded as part of the homework. IMPORTANT: For problems 3.1 - 3.8, solve using MESH CURRENT not NODE VOLTAGE!
