ECE 5224 Non-Linear Communication Circuits (3C)

Advanced methods of analysis and design of communication circuits with emphasis on nonlinear effects and filtering. Nonlinear device models and their use in the design of oscillators and mixers at HF through UHF frequencies. The design of power amplifiers.

What is the reason for this course?

This course provides an in depth coverage of nonlinear communication circuits. These circuits are the building blocks of modern communications equipment used for commercial radio and TV to satellite systems. It is the basis of the graduate work in communication circuits along with the course EE 5214.

Typically offered: Fall. Program Area: Electronics.

Prerequisites: 4605.

Why are these prerequisites or corequisites required?

EE 4605 provides an introduction to the material covered in the course. These principles are expanded and then applied in a rigorous manner to nonlinear analysis.
