ECE 3110. Introduction to
Digital Systems. Lecture 3. Credit 3.
Prerequisite: ECE 2010. Basic concepts in the design and analysis of
digital systems. Number systems and codes. Combinational circuit analysis
and design using Boolean algebra. Sequential logic circuit analysis. |
|
|
This course introduces the concept of digital systems and
the fundamentals of digital logic analysis and synthesis. It provides a
foundation for understanding and designing a broad range of devices,
ranging from small special-purpose digital systems to large
general-purpose digital computers. These systems may consist of a single
custom integrated circuit (IC), a programmable logic IC, a small PC board
with several types of devices, or a large cabinet with dozens of boards
and thousands of ICs.

Several teaching methods will be utilized in an attempt to best match
each student's learning style. These include using the World Wide Web
pages at http://iweb.tntech.edu/rhaggard/311S05,
PowerPoint lecture slides,
computer graphics, class and small group discussion, and homework
assignments (reading, problem solving, and design). Active student
participation in class is at the heart of this educational method and will
be expected.

A significant part of your grade will consist of
a small design project. Combinational digital systems will be
designed which include practical design issues with some
realistic design constraints such as device timing, speed, size, and cost.
You will determine the characteristics of the
system and provide an acceptable solution that is bounded within the
confines of the constraints. The project will help you to assimilate the
different concepts learned in the course and to develop and utilize your creativity.

The homework in this class is intended to give the student practice in
digital system analysis and design. It will include standard pencil-and-paper problems as
well as Altera PLD design and simulation work.
Note that in-class discussion, quizzes, and exams will be very similar to
the homework, so be sure you can do the homework! Students are encouraged to work together
on homework for the
purpose of learning, not copying.
Homework and quizzes will be collected
and graded. Considerations in grading include use of the most
appropriate method, proper notation, correct format, neatness, and clarity of
presentation, as well as correctness of the answer (of course). Follow the
rules in the "Homework, Quiz, Exam Format"
section below for all work submitted.
Due to limited class time, homework and quiz solutions will NOT
be discussed in class, unless there was a general misunderstanding by many
students. Anyone who needs help should attend the review&help session
(see below) or consult the professor during his office hours.
The professor plans to teach an OPTIONAL one hour review&help
session approximately once a week to help anyone who needs it. Bring
your questions about upcoming homeworks, quizzes, and exams or about solutions to
previous work that has already been graded. No new material will be
covered and attendance is not required. The sessions will be scheduled the
day before each homework due date and exam date. It will be held in
a classroom at times to be announced, such that most of you should
be able to attend. The professor will still have normal office hours for
those who want help but cannot attend these sessions. If no one attends,
of course the sessions will be cancelled.
Late Homework:
 | To receive full credit, homework must be turned in at
the beginning of the class period on the date it is due. If turned in
within 24 hours after the beginning of the class period, 33% will be
subtracted from the total possible points. Every additional 24 hours
that a homework assignment is late will result in a loss of an
additional 33%. If I find homework submitted under my door, it will be
considered to be turned in when I discover it, not when you put it
there. Late homework should be turned in at the ECE office. Ask the
receptionist on duty to note the time and date it is submitted. |
| You can submit the homework early (before the due
date) to me in class or to the ECE office. However, I do not encourage
you to turn work in early unless you are going to be absent from class
on the due date. Some students entrust a classmate to bring their
homework to class and turn it in on time. |
| Each homework assignment is normally issued on the
day that relevant material is covered. If you do not work on your
homework until the night before it is due, that can be a disastrous
choice. First of all, if you have problems, you have little or no
chance to see me for assistance. Moreover, I may not have a chance to
respond to email about homework when that email arrives the night
before homework is due. Second, if other events occur unexpectedly,
such as a computer crash, those events will not be accepted as excuses
to turn your homework in late. Unacceptable excuses also include
events like being overloaded or extracurricular activities. For
example, if you need to miss class due to a conference or an athletic
event, your homework must be turned in by the due date to avoid a late
penalty. Note that if I give you an excuse to be absent for class,
that excuse does not automatically become an excuse to turn homework
in late, unless I have explicitly extended the excuse to the homework. |
| I will extend the due date for individuals when an
acceptable excuse is given. To be acceptable, an excuse must
incapacitate you for a couple of days or more. A serious illness or a
death in your family are examples of acceptable excuses. To be
accepted, an excuse must be in writing. It must state how your
"condition" incapacitated you and thus prevented you from
completing your HW assignment during the time between the issue date
and due date you had to complete the assignment. It must include
contact information from a 3rd party, such as a health care provider. |

All exams must be taken at the scheduled time. The final exam will be
comprehensive. Follow the rules in the "Homework, Quiz, Exam Format"
section for all work submitted. If your grade on the final exam is higher than
one of your other exam grades (
exam1, 2 or 3), the final exam grade will replace the lowest earlier grade
(essentially counting the final grade twice). A missed exam,
with a grade of zero, becomes the lowest earlier grade. Note that makeup
exams are not given. The final exam effectively becomes your makeup exam.
If you miss more than one exam, special arrangements will be made if all
the exam absences are for certifiable reasons that are acceptable to the
professor.
Each exam, except the final, may be re-worked and
submitted for re-grading ONE time, anytime within one week of the date
they were distributed by the professor. A maximum of 25% of the original
points lost may be regained. The original exam must not be modified, and
all new work must be done on separate sheets, labeled as REWORK, then attached to the
original exam to turn in.
Copies of old exams are available on the
web page so you will know what to expect. You are encouraged to review these
carefully! You should ask the professor to check your answers before you
take the real exam.
Due to limited class time, exam solutions will not be
discussed in class, unless there was a general misunderstanding by many
students. Anyone who needs help should attend the review&help session
(see above) or consult the professor during office hours.
Any type of calculator may be used, but only on specific exams and/or
problems.

|
| A portion of each homework and quiz grade is awarded for
following instructions. |
| For handwritten work, use one side only of 8
½ x 11 inch green engineering paper. |
| Include this information at the top of the first
page: Name, Course Number, HW/Quiz/Exam Number, Due Date. |
| Staple the pages together in the upper left hand
corner. |
| I strongly suggest that you do your writing in
pencil. You may use different colors. but do not use red. |
| Stay within the margins for the work presented on
each problem. |
| If your penmanship is legible, it is permissible to
use cursive writing. Otherwise, use block lettering. |
| The assigned problems should appear in the order they
are listed in the assignment. Put a box around the problem number when
each problem first begins. It is desirable, but not required, to start
a new page at the beginning of each problem. |
| For short answers, highlight your the final answer
with double underscores or enclose it in a box. |
| Each solution should be presented in detail. Relevant
equations should be written down, and short narrative phrases should
be given wherever it helps to explain the steps you are taking. SHOW
YOUR WORK! |

If you feel that the points awarded on one
or more problems in a homework, quiz, or exam is lower than it should be, you can
request that your grade be reconsidered. This formal method helps
avoid any miscommunication and misunderstanding that might occur with a
more casual request.
There is a "statute of limitations" for grade
reconsiderations. You must submit your request for reconsideration no
later than 1 (one) calendar week after the date that the graded work was returned to the class. After that date, I will entertain
technical questions about graded work only for the
purpose of helping you understand the material. After the 1 week period
has elapsed, I will not entertain requests for grade reconsiderations.
To request reconsideration, use white 8 1/2 x 11 inch
paper to write down why you should have received more points. Please do
not write anything on the original homework, quiz, or test paper. If part of your
rebuttal requires you to work out equations to demonstrate some point, put
that work on the white paper. If you need to refer to a specific place on
your homework or test paper, use a highlighter to mark the place on the
graded paper. Use a paper clip to attach the white pages to the homework
or test paper and hand them to me directly. It usually takes several days
for a grade rebuttal to be processed and returned to you. If you
anticipate that you will need the paper to study for an upcoming test, you
should make yourself a copy of the graded paper to keep before you submit
it for reconsideration.
It is important to me that you receive the grade
you deserve according to the criteria I have established. I do not feel
badly towards you if you request a grade reconsideration. On the contrary,
I feel badly if you erroneously received a lower grade than you deserve.
Hence, in order to encourage you to request a higher grade if my criteria
has not been followed, I make the following promise: Once graded papers
have been returned to the class, I will not lower your grade under any
circumstances except for academic misconduct (cheating). For example, if
you submit a request for reconsideration, and I find that instead of
giving you more points, I should have actually taken away more points, I
will return your paper to you with no change in the grade. If your
rebuttal is that someone else did comparable work and received a higher
grade, please submit that person's paper along with your paper. The other
person should not fear that I will lower their grade. The worst that can
happen is that I will conclude that the higher grade received by the other
person should have been lower. In that case, I will return both papers
with no change in either grade. Finally, please remember to be civil when
you request a grade reconsideration.

It is expected that students will attend all classes. Remember, YOU
are paying for this course. Part of your grade depends on work done in
class, including attendance, which cannot
be made up. It is your responsibility to learn any missed material. You are also expected
to be present at the specified class time; tardiness disturbs everyone.
I go by Official U.S. Central Time, not by the clock in
the classroom or other time references. If you need to leave class early,
please let me know at the beginning of the class period. If you need to
leave the class for a few moments (for example, to go to the rest room),
no permission is required.

Regarding cell phones, PDA's,
"Dick Tracy wrist watches", "Borg implants" and other
personal electronic devices (PEDs):
During lectures and recitations: In consideration of
others, I ask that you make sure that all of your PEDs do not emit noise.
In particular, please make sure that your cell phone is set to vibrate
only. If your cell phone goes off, please step outside the classroom to
take the call.
During Tests: All types of PEDs must be inaccessible. In
particular, if you have a cell phone on your person, it must be powered
off so that it cannot be used to communicate. It must also be stowed away
out of sight. If you are caught with a cell phone (turned on and/or
accessible), I will treat it as a case of cheating in the same way that
accessibility to a crib note is treated.

Students with disabilities (as defined by the
Americans with Disabilities Act) requiring accommodations should
contact the Office of Disability Services (ODS). An Accommodation Request (AR) should be completed as soon as possible, preferably by the
end of the first week of the course. The ODS is located in the Roaden
University Center, Room 112, phone 372-6119. The professor will make
reasonable adjustments to take into consideration the specific handicap of
each disabled student.

Integrity is a principal characteristic of professional engineers;
without it, your work means nothing. The TTU Policy Manual states: Plagiarism,
cheating, and other forms of academic dishonesty undermine the integrity of the academic
process, and cannot be tolerated in an institution of higher learning. ... All forms of
academic dishonesty are prohibited. Students involved in academic misconduct, either
directly or indirectly as a participant or abettor, are immediately responsible to the
instructor of the class, who has the authority to assign an "F" or a zero for
the exercise or examination, or to assign an "F" for the course.
All work submitted must be the product of each individual student's
scholastic effort. This especially prohibits any form of plagiarism,
including copying any part of homework, exams, or computer design files,
whether obtained from other students or over the Web. Cheating
occurs when any student obtains unauthorized assistance or submits work done
wholly, or in part, by anyone else. Anyone who willingly, or through
negligence, provides such unauthorized assistance to others is also guilty
of academic misconduct. Thus, be aware that copying text, designs, or other types of solutions
in any format from the Web
is also plagiarism! Always protect your own work from wandering eyes, since it is often not possible to
determine who was the originator and who was the copier. The first academic
misconduct offense will
result in a failing grade and a letter of reprimand in your permanent student file.
