ENGRI/ECE 1260: Introduction to Signals and Telecommunications
Introduces the concepts that underlie wired and wireless communication systems. Students achieve a rudimentary understanding of basic ideas such as coding and data compression; frequency content, bandwidth, and filtering; sampling and reconstruction; and time- and frequency-division multiplexing. Discussions of practical applications focus on areas such as the public switched telephone network, ISDN, ATM, and TCP/IP. Students also develop an appreciation for the historical development of the field. The course includes both lectures and laboratory demonstrations.

ENGRI/ECE 1280: Security, Privacy, and Information Network Design: Wiretaps to Facebook
An introduction to security and privacy issues in networking technology. With an emphasis on the Internet and 3G/4G cellular, we explore technologies for securing networking infrastructure and keeping personal information private. Symmetric and asymmetric (public-key) cryptography and its implementation are introduced, including hardware considerations. The question of privacy in a networked world is covered from a variety of perspectives, including the social and economic costs of both the invasion and preservation of privacy. We see how economic, legal, and societal issues emerge when engineering design choices infringe upon user privacy. Privacy-aware network design practices are considered.

ECE 4110: Random Signals in Communications and Signal Processing
Introduction to models for random signals in discrete and continuous time; Markov chains, Poisson process, queuing processes, power spectral densities, Gaussian random process. Response of linear systems to random signals. Elements of estimation and inference as they arise in communications and digital signal processing systems.

ECE 4450: Computer Networks and Telecommunications
This is a basic course in networking with an emphasis on the Internet.
