ELEC 226: Circuit Theory II
Bucknell University, Spring 2012


Course Objectives:

Students finishing this course will understand fundamental circuit analysis techniques, including transient, s-domain, and sinusoidal steady-state methods. Students will be prepared for junior-level courses in electronics (ELEC 350) and signals and linear systems (ELEC 320).

Prerequisites:

ELEC 120, ELEC 225, and MATH 201, 202, and 211. Corequisite: MATH 212.


Required Textbook:

Circuits by F.T. Ulaby & M.M. Maharbiz, National Technology and Science Press, 2009.

The library has many books on circuit analysis. I encourage you to read a variety of books in order to see different explanations and additional examples.


Course Web Page:

The web page for the ELEC 226 course is located at
http://www.linux.bucknell.edu/~kozick/elec22612
It can also be accessed by following the link from
http://www.linux.bucknell.edu/~kozick

The course home page contains homework assignments, syllabus, laboratory assignments, and other course information. Homework solutions will be posted on Moodle.

Grading:

Grades for the course will be determined as follows. 

Two in-class exams (20% each)              40% 
Final exam                                 25%
Homework and brief, in-class quizzes       20%
Laboratories                               15%


Exams and Quizzes:

Two in-class exams will be given on the following dates:
Thursday, February 23 March 1 and
Tuesday, April 3 10.
The course will conclude with a comprehensive final exam.

Short quizzes (announced or unannounced) may also be given to check your understanding of the material as we proceed through the course. Missed quizzes cannot be made-up, but your lowest quiz grade will be dropped.


Homework:

Homework will be assigned regularly to give you practice with the course material. It will be due at the beginning of class on the specified due date. Late assignments will not be accepted because solutions will be posted on Moodle and reviewed during class on the due date. The final homework grade is computed as follows. If there are a total of P points on N homework assignments, then your total homework points H are converted to a percentage as (H/P)*N/(N-1)*100%. Therefore if you miss a total of (P/N) points on the homework (corresponding to the average value of one assignment), then your overall homework grade is still 100%. The maximum homework grade is 100%.

You are allowed and encouraged to work on the homework with groups of your classmates. The purpose of the homework is to practice with the material and to improve your understanding. I encourage you to learn from each other, and also to see me for help when you have questions. However, the homework solutions that you submit for grading must be written individually. Be sure that you understand the reasoning for each problem, even if you initially solved the problem with help from your classmates.


Laboratories:

Each student will attend a laboratory session every other week, with the schedule available on the Laboratories link on the course web page. Students will work in pairs (or groups of three if necessary) on the labs for this course. Some of the lab exercises will serve as illustrations of the course material, while others may be design projects in which you choose the topic.

Attendance at all laboratory sessions is expected and required. If you have a legitimate reason for missing lab, please see Prof. Kozick as soon as possible to make arrangements for making up the lab session.

Each student should keep a lab notebook for this course, but I will not collect your notebooks for grading. The lab notebook will serve two purposes. First, it is a good way to organize the notes and data that you'll need to prepare the lab report. Second, it provides a good reference for future labs that you can use to remember how to perform certain operations with the instruments.

The lab report requirements will be specified for each lab exercise. The reports will range from a brief summary of your activities to a more comprehensive documentation of your analysis, design, and measured results.



ABET Course Outcomes:

Please see the ABET link on the course web page.

Tentative Outline:

The course topics will be chosen from the following chapters in the Ulaby/Maharbiz text. Chapter 13 on Magnetically Coupled Circuits will be distributed as a PDF file.

We will not have time to cover all of this material. However, Chapters 10 and 11 will be covered in your junior-level course, ELEC 320 (Signals and Linear Systems).

Chapter 7:
Review of phasors, impedance, and circuit analysis methods.

Chapters 8, 9, and 13:
Instantaneous, average, reactive, complex, and rms power; power factor; maximum power transfer; frequency response, filters, Bode plots; magnetic circuits, transformers.

Chapters 5 and 6:
Time-domain (differential equation) analysis of (passive) RC, RL, RLC, and (active) op amp circuits; time constants.

Chapters 10 and 11:
Laplace transform: s-domain circuit analysis (complex frequency, poles and zeros, transfer function), convolution; Fourier series and transform.
