Prerequisite: EE 373

Coordinator: Ayşın Ertüzün, Professor of Electrical Engineering

Goals:   In this course, the communication systems will be studied from a systems point of view, emphasizing mathematical descriptions, representations, and processing of electrical signals that characterize such systems. 

Learning Objectives:

At the end of this course, students will be able to:

1. Find frequency representation of deterministic signals and LTI systems
2. Design filters with a given amplitude and phase response
3. Design analog modulators and demodulators from a system point of view
4. Design digital modulators and demodulators from a system point of view

Prerequisites by Topic:

1. Signals and System
2. Fourier Series and Fourier Transform
3. Linear Circuits and System

Topics:

1. Review of Signals and Fourier Series and Fourier Transformation, Generalized Orthogonal Transformation (1.5 week)
2. Analysis and Transmission of Signalsand Design of Filters (1.5 week)
3. Amplitude (Linear) Modulation (2.5 weeks)
4. Angle (Exponential) Modulation (2.5 weeks)
5. Sampling, Quantization, Pulse Amlitude and Pulse Digital Modulation (3 weeks)
6. Signalling Schemes (1 week)

Course Structure: The class meets for two lectures a week, each consisting of two 50-minute sessions. 5-6 sets of homework problems are assigned per semester.  There are two in-class mid-term exams and a final exam.

Computer Resources:

Laboratory Resources: None.

Grading:

1. Homework sets (10%)
2. Two mid-term exams (25% each).
3. A final exam (40%).

Outcome Coverage:

• Apply math, science and engineering knowledge.  This course is about representation of signals in terms of Fourier Series and Fourier Transformations. The students must be able to go back and forth in time and frequency domains and represent signals in both domains. They should comprehend continuous time signals, sampled signals, discrete-time signals and digital signals both in time and in frequency domains. These concepts are heavily emphasized during lectures, in problems assigned and in exams.

• Design a system, component or process to meet desired needs. The students must be able to design modulators for analog modulation schemes as well as pulse analog and digital modulation schemes.
