Professional Component

Contributes toward the Electrical and Computer Engineering Topics Courses and Major Design experience.

Design Content Description
Approach:

The course focuses on developing a thorough understanding of communication systems by using a series of specific examples and problems. These illustrate and require the student to understand analysis and design of modern communication systems. The course focuses on design of basic communication systems in building blocks. Specific examples include modulators, multiplexers, phase locked loops, and radio and television systems. These and other design examples make up 50% of the lecture time and 50% of the homework problems.
