EECS 864 Homework Rules
   All work containing more than one page must be stapled - no paper clips and no folded
    corners. In order to facilitate grading of homework problems, homework
    shall meet the following specifications:

    1. Written (single-sided) on 8.5"x11" paper.

    2. For text and equations, typewriten or use an HB or No. 2 pencil (or darker), or blue or
    black ink. (Pencil is preferred.) No other colors please, except in diagrams or
    graphs.

    3. All pages should be numbered i/j in top right hand corner, with your name
    appearing at the top of each page. It is O.K. to use your initials after the first
    page.

    4. All work must be shown for full grade - be as thorough as possible.

    5. Writing should be legible and literate - if the grader cannot read your
    handwriting,you will receive no credit for the problem.



                                                                                    Introduction   6
EECS 864 Homework Fromat
 6. Answers are to be boxed and right justified, with the variables, values (if any) and
 units (if any), included in the box. Right justified means placed on the right
 side of the page.

 7. Leave half an inch between consecutive parts of a question, and draw a line
 across the page at the end of each complete question.

 8. No part of a question should appear in any margin of the paper.

 9. Diagrams and graphs should be of a good size (say at least 3x5 sq. inch), and
 may contain colors. Diagrams and graphs must be titled, labeled, and clearly
 drawn. Tables should also be titled.

 10. Graphs should be scaled (put number on axes), labeled (put names /units on
 axes), and titled at the bottom of the graph. Any graph which occupies an area
 of less than 3x5 sq. inch and which is not titled will not be graded.

 11. Where possible use conventional units such as bits/sec, Hz and km

Student Lectures
   To be done in power point
   To include specific examples to illustrate the
    concepts.
   No overview only lectures, must include
    examples, must go beyond just summarizing
    a paper/algorithm.
   Goal is to educate the class about the topic.
   Each student will provide the class with
    references to their lecture material.
