**Course Description:** This is the second electronics course. It is designed for the students in the
Electrical/Computer Engineering emphasis.
The course expands on the introduction to diodes, field effect and
bipolar junction transistors, and op-amps in Electronics I. MOSFET transistors are emphasized as dc biasing,
amplifier configurations, ac equivalent circuits, and frequency response are explored.
Ideal op-amp circuits are quickly reviewed and then the circuitry inside
the op-amps, feedback and stability, and the non-ideal effects in op-amp
circuits are studied. Finally, typical
applications of op-amps are introduced and the design considerations are
explored. This is a 4 credit course with
3 one-hour lectures and a three-hour lab each week.

**Course Prerequisites: **ENGR275 Electronics I or its equivalent is a
prerequisite.

**Course Procedures:** Some of the course procedures that we will be
following are listed below.

*Attendance*–You are expected to attend each class and participate
in the class and lab activities conducted.
Assignments for individual or group presentations at the next class will
at times be given. Successful
presentations of these assignments will be a part of the homework grade for the
class.

*Intellectual
Honesty– *Any work that you submit is
expected to be your work and not something that you have “borrowed” from
others. I encourage you to collaborate
in your work, but not to copy the work of others. On exams I expect that you will follow the
exam instructions carefully and not use materials other than those
specified. Deviation from these
expectations may result in a failing grade on the assignment or even for the class. For further information on the issue of
academic integrity please read the Academic Integrity section in the Bulletin
on page 28 and the corresponding section in the Student Handbook.

*E-mail
Contact–*I welcome your questions via
e-mail and will suggest that you check your e-mail between class sessions for
further clarification of assignments or tips that may help you do the
homework. Be sure that you are
“connected”!

*Homework*-- Questions and problems at the end of the chapters
will be assigned in class and will be expected to be handed in at the __beginning__
of the next class period unless otherwise indicated. If you have trouble with
the homework, I will try to be of assistance via e-mail or by phone or in
person in the office. __Late papers, if
accepted, will be given ½ credit.__

*Laboratory*–Laboratory project outlines will be given out each
week. You will be expected to complete
each of these projects. For each project
you will hand in a report with these elements: A) a description of the project,
its objectives, and the steps that you went through to complete it, B) lists of laboratory equipment used and
schematics of circuits you put together, C) documentation of results of the
tests you conducted including labeled waveforms and tables of measurements, and
D) a summary of your results with your comments on what the results mean and
how you were able to meet the objectives of the project. These reports are to be created on some type
of word processor with attention to spelling, grammar, and overall report flow
and organization. They should stand
alone, being able to define what you did and your results completely.

*Exams*–Exams will be announced at least a week in advance
and will emphasize the material covered since the last exam. Refer to the course objectives to know what
you will be expected to do. It should
be recognized that the material at each stage builds on the previously covered
material so in that sense each exam will cover all of the previous material.

*Students with
Disabilities–*Andrews University accepts and appreciates diversity in its students,
including students with disabilities. Accordingly, students with documented
disabilities are encouraged to inform the University of their disability and enter into a dialogue regarding ways in which
the University might reasonably accommodate them. If you qualify for
accommodations under the Americans with Disabilities Act, please see the
instructor as soon as possible for referral and assistance in arranging such
accommodations.

**Course Grading Procedures:** The final grades will be computed by weighting the
total scores on your attendance, your daily homework and reading assignments,
your laboratory assignment reports, and your exams by the factors indicated and
then comparing your overall percentage with the scale shown.

**Weighting factors: Grading
Scale:**

Homework/Quizzes 25% 90 -
100% A

Lab project reports 25% 80 - 89% B

Exams 50% 70 - 79% C

60 - 69% D

< 60% F
