- Fall 2001: E3203 Signals and Systems II
- This second part of the two-part “Signals and Systems” sequence focuses on discrete-time signals and systems (the emphasis on the first part is continuous-time signals and systems). The course provides the necessary terminology and mathematical tools for the modeling and analysis of discrete-time signals and systems. Material covered includes time-domain analysis of discrete-time systems, Fourier analysis of discrete-time systems, discrete-time system analysis using the Z transform, frequency response and digital filters, as well as state space techniques.
- Spring 2002: E1201 Introduction to Electrical Engineering
- This lab-oriented course introduces basic concepts of electrical engineering
and discusses their application in real systems. The course introduces electrical
variables, circuit laws, nonlinear and linear elements, ideal and real sources,
transducers, operational amplifiers in simple circuits, external behavior
of diodes and transistors, first order RC and RL circuits. It also addresses
the digital representation of a signal, digital logic gates, and flip flops.
A laboratory and final lab-based project are an integral part of the course.
Among the various interesting circuits that students build in the lab are
audio amplifiers and filters and AM radio receivers.
The course is offered to freshman and sophomore students prior to their selection of an engineering major. Its objective is to provide a thorough introduction to the various aspects of the electrical engineering discipline, aiding the students in the selection of their major. This course is among the most popular in the school, with over 100 students.

- Fall 2004: E6885 Design of Multimedia Services (New course)
- A senior graduate level course that examines the design of multimedia services, i.e., services that involve video and/or audio communication possibly combined with graphics, text, and images. Specifically, the course examines how individual components such as video and audio codecs, transport protocols and communication networks in general, as well as software development environments, are brought together to implement a variety of important services that we all use (or will use) every day: from interactive TV and DVDs to 3rd generation mobile phones. Emphasis is placed on the integration and application development aspects of these systems.
Prerequisites are: a course on digital signal processing (E4810) or digital image processing (E4830); a course on computer networking (E6760 or CS W4119); a course on probability and stochastic processes (E6711); one software development course beyond basic data structures (e.g., on software engineering, operating systems, databases, etc.). Knowledge of video and/or audio coding would be beneficial but not required.
