Calculator

You will need a calculator for this class. It should be able perform arithmetic operations on complex numbers, including conversion form polar to rectangular form, and calculate sine and cosine functions in degrees and radians. The TI-89 is an example of the type of calculator that you will need for this class. The TI-83/84 will also work, but requires more keystrokes than the TI-89.

Course web page

The course web page is located at http://www2.nau.edu/~sh295/EE188. Homework assignments and practice problems will be listed on the course web page. The Vista web page will also contain this information, but the course webpage will be updated first.

Course Description:

Introduces electrical engineering including DC and AC circuit analysis, operational amplifiers, and AC power.

Course Objectives

The student is able to:

  1. Understand fundamental electrical circuit concepts of voltage, charge, current, power and energy and their interrelationships.
  2. Solve problems associated with dc and ac linear circuits that include independent and dependent sources, resistors, capacitors, inductors, and operational amplifiers.
  3. Use mathematical analysis to solve real and complex simultaneous equations.
  4. Have an appreciation for electrical engineering and the impact on one’s personal and professional lives.

Homework

Assignments will be given on a near-weekly basis, generally due two class periods hence. The homework problems will be based on the class lectures and the textbook materials. The assignments will be posted on the course website and in Vista and will be problems from the book, handouts or problems posted in WebWorks. Late homework will not be accepted. Your lowest homework score will be dropped.

The point values of each homework assignment may vary. However, each homework will be calculated as a percentage of points possible on that assignment when determining total homework points.

The total points on the homework will be worth 15% of your grade

The login for the WebWorks site is your NAU ID, the initial password is the last five digits of your student ID number. You may change the password if you want.

Quizzes

Short quizzes will be occasionally be given in class covering previous material. You will be given 10-15 minutes for the quiz. The quiz grades will be worth a total of 10% of the final grade. There will be no makeup quizzes.

Attendance & Class Participation

Students are expected to attend classes. Please be on time - quizzes may be given at the beginning of class and no extra time will be allowed for tardy students

An excused absence will be given to students with a documented excuse. Please notify me ahead of time if you will be missing a class.

Makeup homework/exams will be given only for excused absences.

Academic Integrity

Cheating - claiming another student's work as your own or permitting another student to claim your work.

Plagiarism - claiming another person's writing as your own.

Students are encouraged to work together to solve the homework problems and to study for the exams. Working together does not mean “copying” another person’s work.

Students who are caught cheating will be disciplined according to the NAU Academic Policy.

Policy Statements

These NAU policies will be followed in this class. You may obtain a copy of these policies from http://jan.ucc.nau.edu/academicadmin/policy1.html

SAFE ENVIRONMENTAL POLICY

STUDENTS WITH DISABILITIES

INSTITUTIONAL REVIEW BOARD

ACADEMIC INTEGRITY

Academic Contact Hour Policy

The Arizona Board of Regents Academic Contact Hour Policy (ABOR Handbook, 2-206, Academic Credit) states: “an hour of work is the equivalent of 50 minutes of class time…at least 15 contact hours of recitation, lecture, discussion, testing or evaluation, seminar, or colloquium as well as a minimum of 30 hours of student homework is required for each unit of credit.”

The reasonable interpretation of this policy is that for every credit hour, a student should expect, on average, to do a minimum of two additional hours of work per week; e.g., preparation, homework, studying.

Classroom Management Statement

Membership in the academic community places a special obligation on all members to preserve an atmosphere conducive to a safe and positive learning environment. Part of that obligation implies the responsibility of each member of the NAU community to maintain an environment in which the behavior of any individual is not disruptive.

It is the responsibility of each student to behave in a manner which does not interrupt or disrupt the delivery of education by faculty members or receipt of education by students, within or outside the classroom. The determination of whether such interruption or disruption has occurred has to be made by the faculty member at the time the behavior occurs. It becomes the responsibility of the individual faculty member to maintain and enforce the standards of behavior acceptable to preserving an atmosphere for teaching and learning in accordance with University regulations and the course syllabus.

At a minimum, students will be warned if their behavior is evaluated by the faculty member as disruptive. Serious disruptions, as determined by the faculty member, may result in immediate removal of the student from the instructional environment. Significant and/or continued violations may result in an administrative withdrawal from the class. Additional responses by the faculty member to disruptive behavior may include a range of actions from discussing the disruptive behavior with the student to referral to the appropriate academic unit and/or the Office of Student Life for administrative review, with a view to implement corrective action up to and including suspension or expulsion.

Professional Ethics and Code of Conduct

Exceptionally high standards of honor and integrity are fundamental and essential to the study and practice of engineering. Academic preparation for the profession must be conducted in an atmosphere which fosters these values.

In addition, to compliance with the Student Code of Conduct and Policy that applies to all students at NAU, engineering students are expected to conduct themselves professionally. Violation of the National Society of Professional Engineers (NSPE) Code of Ethics found at http://www.nspe.org/ethics/eh1-code.asp or the Association for Computing Machinery (ACM) Code of Ethics and Professional Conduct at http://www.acm.org/constitution/code.html may lead to dismissal from the College’s academic programs. Copies of these codes are also available in the Office of the Dean.

Violations of any of these codes will be handled as detailed in the publications listed above, and will be documented in the student’s advisement file.

Faculty members may ask students to affirm in writing that they have neither given nor received unauthorized aid on an examination or assignment.

Course LECTURE SCHEDULE

The following course lecture schedule is only a suggestion; as needed, more time may be spent on certain topics and less on other topics. Note that the scheduled exam times (other than the final exam time) are also tentative. At the instructor’s discretion, material outside the book may also be presented. You are responsible for all material presented during lecture.
