Readings: see below

This will be a hands-on, interactive, learn-by-doing course, hence
attendance is mandatory, and absences should result in very low grades.
Grading will be based on quizzes, projects, homework, reports, attendance,
roughly in proportion to the number of class periods devoted to each.
Weighting approximately: projects 40%, quizzes 20%, final project 40%.
Grading option: exceptional students may co-author a March 6 paper with
instructor to http://congress2015.metamorphose-vi.org as a final project.
It is likely that projects and quizzes will comprise the bulk of the grades,
with a final project roughly weighted in proportion to the number
of weeks devoted to the final project (approx. 3-4 weeks).
Grading scale: 90-100 A, 80-89 B, 70-79 C, 60-69 D, with ``curve,''
if any, entirely at the discretion of the professor. Quizzes may
be given without warning. We will also be using the computer lab.

Collaboration (not copying) on homework/projects is encouraged. However,
different project groups may NOT share program code or report material.
Certain assignments may be restricted to independent effort, in which
case collaboration is not permitted. Class attendance and participation
are expected. There is no formal course prerequisite for this course,
but all students enrolling should be thoroughly familiar with analog and
digital communications (ECGR4123), Fourier transform concepts (ECGR3111),
and electronic devices R, L, C, BJT, MOSFET, and their use in circuits.
Review of such topics is the responsibility of the student.

If you miss an exam/quiz for any reason, you will receive a grade of zero
(exceptional circumstances must be documented and/or approved by the
instructor at least 24 hours prior to the exam). Any special exam or project
accommodation request should be made no later than the class meeting one week
before the exam or project. Frequent absence from class or labs may result
in a severe grade reduction. Late projects will not be accepted, or may
be penalized up to 20 percent per day, solely at the instructor's discretion.
Absence from each project session, or early departure before attendance is
taken should result in 100% grade reduction per absence, per day's work
beyond 2 absences. The instructor is free to assign students to any project
group at any time. Appeals regarding final grade must be communicated to
instructor within 14 days after end of semester, since any residual materials
may be destroyed thereafter. If a quiz is given during a "free pass," the
student may, only once, request by email that the next quiz grade be
applied doubly, solely at the instructor's discretion. Departure from
the classroom during any quiz or exam may result in a grade of zero.
Students are responsible for submitting all forms to Disability Services,
and must provide a letter of accommodation from Disability Services in the
first week or two of the semester (see their office for more information).

It is the responsibility of the student to be familiar with the academic
regulations, degree requirements, religious accommodation for students,
course requirements, and all other requirements, policies, and procedures
set forth in the current University Catalog and all University Policies.
The official university guidelines supersede any contradictions that may
exist in this handout. Violations may result in reduction of grades,
zero grade, fines, suspension, course failure, or other adverse consequences.
In addition, a proper classroom environment is expected by all students,
and therefore any disorderly or disruptive conduct or other negative impacts
on the classroom, solely at the instructor's discretion, will result in
expulsion from such class with a grade of zero for corresponding material,
and/or other adverse sanctions as may be deemed appropriate.

If there are any issues or problems within a group, students must
follow the Project Problem Resolution Guidelines provided on the
course website.

The course policies set forth in this syllabus may be modified at any time
by the course instructor. Notice of such changes may be by announcement in
class, website posting, and/or by email to the student's UNCC email address.
