Course Description and General Information

The objective of this course is to provide an introduction to the basic principles in the analysis and design of analog communication systems. I have chosen to cover a wide range of material with the goal of surveying the Analog Modulation techniques.

· Following an introduction, we begin by looking at probability, random variables and random processes to the extent that is necessary for a first course in communications.

· We will then move onto analog modulation techniques, specifically, AM, FM, and PM and their application to radio and TV broadcasting.

· We will then provide analysis of the effects of noise in analog modulation systems.

· Finally, we treat scalar quantization and describe the common wavefrom coding techniques.

Textbook:

· Midterm I 35%

· Final Exam 50%

· Homework 15%

Final Exam - The final exam will cover all of the material covered in class this semester.

Academic Honesty: When working on an assignment, you may consult with the instructor, the TA, classmates or friends. However, all actual submitted work must be your own work.
