Computer Use:
The students will learn to use a software package used to simulate communications systems in the time and frequency domains. This package will be used to perform open-ended design of selected AM, FM and pulse modulation systems. Instructor and students may agree to use MATLAB or other software.

Engineering Design Statement:
In the lectures the students learn techniques for the analysis and basic design of communications systems. In the homeworks they are given the opportunity to use these analytical tools to design simple communications systems which are required to meet a given set of specifications. In these design problems they need to choose between various alternatives to get the best performance within a given set of constraints (power, bandwidth, etc.). These design tasks involve both "pencil-and-paper" design and computer exercises. Approximately 25% of the course grade will be based upon engineering design.
