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.

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.
