EE 350 – Communication Systems                     3 credits                        45 hours

Pre-requisite:  EE 301 – Signals and Systems 1 (may be taken concurrently)             

Description: This is one of several elective Communication Systems courses* in Electrical Engineering.  It begins with a review of Time-Domain Signals and Systems that builds on the background learned in circuits and Signals and Systems.  The body of the course is the study of analog communication systems and the effects of noise on those systems.  Modulation and demodulation techniques (AM, FM, PM) are developed.  Pulse Amplitude Modulation (PAM/Sampling) is discussed in the context of FM Stereo.  Dealing with non-linear system elements is also discussed, including the problems they cause and the opportunities they present.  The Structure and design of the classical “Super-heterodyne” radio is introduced.  A mathematical treatment of the effects of various noise sources on these systems is also covered.  Historical design studies and topics in communication applications are employed to permit the student to apply these concepts to meet system requirements.  Clarity in important concepts is provided through simulation of modulation techniques on multi-media computing systems.
