The Reason this Course is in the Program:

This course introduces communications systems in general to the students who are familiar with electronic circuits which were taught in the second semester of sophomore year. One of its primary purposes is to teach the communication systems in general. Second purpose is to introduce baseband digital modulation and radio frequency modulation technology.
