An integrated, hands-on introduction to electrical engineering and computer science. Lectures and laboratory experiments explore modeling transmission systems in the time and frequency domains, analog and digital signaling, detecting and correcting errors, source coding, and the engineering of packet-switched networks. These explorations are used to illustrate some common EECS themes: the role of abstraction and modularity in engineering design, building reliable systems using imperfect components, selecting appropriate design metrics, understanding the limits imposed by energy and noise, choosing effective representations for information, analyzing the performance and correctness of algorithms, and engineering tradeoffs in complex systems.
