Course Format
This course is intended to be delivered in a in-person format,but may go fully
online as needed or as directed by the university. Various course components
may be delivered online (through Canvas and the course website), and other parts
should be conducted in the classroom, with social distancing guidelines applied.
The components of this course are meant to provide students with some
flexibility in their learning. The course is designed to engage students in a
process of pre-class activities, in-class activities, and post-class activities,
including projects and supplemental videos. In the event of
all-online classes, it is likely that weekly or topical videos will be
made available, and class-meeting time zoom/etc sessions will be used for
questions, quizzes, projects, etc. Any online, or face-to-face class may
be recorded, with copyright by Thomas P. Weldon, all rights reserved.

Internet requirement: you will need reliable high-speed access.
Exams may be open book, NO calculators. Plan is to allow hardcopy of one 
or both of the above books during exams/quiz.  
Quizzes may or may not be announced. Grading: Exam1 30%, Exam2 30%, 
Homework/Quizzes/Projects/etc 40%. NOTE: instructor may change weights.
Scale: 90-100 A, 80-89 B, 70-79 C, 60-69 D, with "curve," 
if any, entirely at the discretion of the instructor.  See prior year 
projects, exams, handouts, quizzes on website. For potential
documented covid absences, one quiz grade will be dropped for all
students, so save this option for any covid absence. Similarly,
project submissions may be delayed one week, and/or makeup exams will
be prepared, but only for covid case with acceptable documentation
emailed to the instructor before the project due date or exam date.

The College of Engineering requires all students to own a laptop
computer, and students must bring a laptop to every class meeting,
since all quizzes/exams/projects are planned to be online, even
in the classroom. Students without a laptop during any quiz or exam
will receive a grade of zero or other sanctions.
Collaboration (not copying) on homework and projects is encouraged. 
However, different project groups may NOT copy program code or report material. 
Class attendance and participation are expected.  You must read the textbook; 
it is impossible to cover all material during class.
The course will roughly follow the outline below; some key topics are noted.

Final Exam      See Video Presentation and Review below               

Video Presentation and Peer Reviews (subject to change): 
     Topic TBD (non-Foster antenna bandwidth).
     Every group must upload a 5 minute optionally-anonymous video of a 
     presentation on/before 5 PM of the night before the scheduled final 
     exam, so that all videos will be ready online for peer review during
     the scheduled final exam meeting time.  In addition, a pdf of the 
     presentation slides must be emailed to the instructor by the same 
     deadline (as a backup in case of video technical difficulties).
     As an online final examination class session, each individual student
     must view randomly assigned videos during the final exam period, 
     and/or take an online quiz at instructor discretion. The video and
     reviews will be worth approximately one quiz.   
Excused absence makeups: May be scheduled for the last class period.
Makeups will usually cover cumulative course material.

COVID-19 Protection:
It is the current policy of UNC Charlotte that as a condition of
on-campus enrollment, all students are required to engage in safe
behaviors to avoid the spread of COVID-19 in the 49er community.
Such behaviors specifically include the requirement that all students
properly wear CDC-compliant face coverings in all indoor spaces
on campus, including classrooms and labs, regardless of vaccination
status. Failure to comply with this policy in the classroom or lab
may result in dismissal from the current class session. If the
student refuses to leave the classroom or lab after being dismissed,
the student may be referred to the Office of Student Conduct and
Academic Integrity for charges under the Code of Student Responsibility.

Students are expected to attend every class and remain in class for
the duration of the session when it is safe to do so in accordance
with university guidance regarding COVID-19. Failure to attend class
or arriving late may impact your ability to achieve course objectives
which could affect your course grade. An absence, excused or unexcused,
does not relieve a student of any course requirement. Regular class
attendance is a studentís obligation, as is a responsibility for all
the work of class meetings, including tests and written tasks. Any
unexcused absence or excessive tardiness may result in a loss of
participation points. Students are encouraged to work directly with
their instructors regarding their absence(s). For absences related to
COVID-19, please adhere to the following:

1)Complete your Niner Health Check each morning.
2)Do not come to class if you are sick. Please protect your health
  and the health of others by staying home. Contact your healthcare
  provider if you believe you are ill.
3)If you are sick: If you test positive or are evaluated by a
  healthcare provider for symptoms of COVID-19, indicate so on your
  Niner Health Check to alert the University. Submit a copy of your
  Niner Health Check notification email to your instructors. Upon
  learning that you have tested positive or have been diagnosed for
  symptoms of COVID-19, either from your reporting or from Student
  health Center testing or diagnosis, representatives from Emergency
  Management and/or the Student Health Center will follow up with you,
  and your instructors will be notified of the need for accommodations,
  as necessary.
4)If you have been exposed to COVID-19 positive individuals and/or have
  been notified to self-quarantine due to exposure, indicate so on your
  Niner Health Check to alert the University. Representatives from
  Emergency Management and/or the Student Health Center will follow up
  with you as necessary. Submit a copy of your Niner Health Check
  notification email to your instructors. If you need any additional
  support verifying your absence after you have communicated with your
  professors, contact Student Assistance and Support Services.
5)To return to class after being absent due to a period of self-
  quarantine, students should submit a copy of their Niner Health
  Check clearance email to their instructor(s). To return to class
  after being absent due to a COVID-19 diagnosis, students should
  submit an online request form to Student Assistance and Support
  Services (SASS). Supporting documentation can be attached directly
  to the request form and should be from a student's health care provider
  or the Student Health Center, clearly indicating the dates of absences
  and the date the student is able to return to class. Instructors
  will be notified of such absences.
6)If you are absent from class as a result of a COVID-19 diagnosis or
  quarantine, as instructor I will provide access to videos to help you
  continue to make progress in the course. The final decision for
  approval of all absences and missed work is determined by the instructor.

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 meting one week
before the exam or project. Late projects will not be accepted, and/or may
be penalized up to 30 percent per day, solely at the instructor's discretion.
Absence from class sessions or internet sessions may result in grade reduction.
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. Departure from classroom during any quiz or exam will
result in a grade of zero. Students are responsible for submitting all
forms to Disability Services, and must provide a notice of accommodation
from Disability Services in the first week or two of the semester (see
their office for more information). Audio or video recordings are not
permitted, and all course content are copyright by Thomas P. Weldon.
If any recording is permitted in writing, such recording remains
copyright by Thomas P. Weldon and shall not be distributed.
NOTE: Final grading may include a subjective component, at instructor
discretion, based on the above rough weightings PLUS the instructor's
overall evaluation of student performance in projects and class

This syllabus contains the policies and expectations established for this
course. Please read the entire syllabus carefully before continuing in this
course. These policies and expectations are intended to create a productive
learning atmosphere for all students. Unless you are prepared to abide by
these policies and expectations, you risk losing the opportunity to
participate further in the course.

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. Use of
computers, tablets, phones, etc. during class are disruptive to other
students in class, and may be prohibited case-by-case solely at instructor's
discretion. 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, by canvas, and/or by email to the student's UNCC email address.
