Textbook: Principles of Communications, Rodger E. Zimmer and William H. Tranter, John Wiley, 5th  Edition, 2002.

 

Course Objectives: This course provides a fundamental background in analog and digital communications. Basic concepts regarding modulation and demodulation schemes, performance of communication systems under noise are introduced.

 

Requirements: There will be two midterm exams, bi-weekly quizzes, one final exam and weekly homework assignments.

 

  1. Homeworks: Homework assignments will be given every week and will constitute 10 percent of your final grade. The homework questions will be posted on the web with their due dates. Posting of new assignments will be announced in class. You must submit your homework during the class period on the due date.  No late homework assignments will be graded. The lowest homework score will be dropped when computing your average homework grade. Homework solutions must be original copies in the student’s own handwriting. No other submissions will be graded. Solutions must be clear and neatly written to receive credit. Solutions to homework assignments will be posted on the web.
  2. Exams: There will be two midterm exams (one class period each), and a final exam. The midterm exams will count 50 percent and the final exam will count 30 percent toward your final grade. A makeup exam, which will be given only in legitimate cases of illness or personal emergency which is documented by a physician or other appropriate official, will take place during the last week of the semester. This exam will take the place of any missed midterm and will be comprehensive. A student who finds it necessary to miss a midterm should contact the professor before the exam to explain the circumstances. A student who must miss the final exam should contact the professor as well as the Dean’s Office, according to MSU policy.

3. Quizzes: There will be unannounced quizzes in class about every other week. The quizzes will be 10-15 minutes long and will be based on the homework assignments. The quizzes will count 10% toward your final grade.

 

Midterm exam 1- February 25 10:20-11:10 a.m. 25%

Midterm exam 2- April  8 10:20-11:10 a.m. 25%

Final Exam- May 3 10:00-12:00 p.m. 30%

Homework 10%

Quizzes 10%

 

Incomplete grades will be given only in unusual cases of illness or other personal emergency which causes the student to miss a significant amount of the course. This grade cannot be given for any other reason. A student who misses the final exam without satisfactory explanation will receive a failing grade in the course according to MSU policy.
