### ECE 2704 Signals and Systems (3C)

Analysis techniques for signals and systems. Signal representation, including Fourier and Laplace transforms. System definitions and properties, such as linearity, causality, time invariance, and stability. Use of convolution, transfer functions and frequency response to determine system response. Applications to circuit analysis. Hands-on projects to illustrate and integrate the various concepts.

What is the reason for this course?

This course introduces the mathematical analysis tools needed for the study of signals, signal processing, system description, and system response. These tools include Fourier methods, Laplace transforms, and frequency response concepts that constitute the fundamental analysis methods in all of engineering. Course concepts are illustrated and integrated by means of a couple of hands-on projects. This course prepares students for further study in all areas of electrical engineering, but is especially critical in communications, control systems, and electronics.

*Required for all EE and CPE majors*. Typically offered: Fall, Spring. Program Area: Systems/Controls.

*Prerequisites: C- or better in 2004, 2074, MATH 2214*.

Why are these prerequisites or corequisites required?

This course requires the students to know basic circuit analysis methods, differential equations, and complex numbers. Because this material is traditionally taught in the first and second years of the engineering curriculum, the student must have sophomore-level skills in order to successfully complete this course.
