ECE 3704 Continuous and Discrete System Theory (3C)
Continuous- and discrete-time system theory. Block diagrams, feedback, and stability theory. System analysis with Bode diagrams. Discrete-time stability, difference equations, Z-transforms, transfer functions, Fourier transforms, and frequency response. Sampling of continuous systems and an introduction to digital filtering.
This course introduces the practical applications of signal and systems analysis in continuous and discrete time. Whereas EE 2704 introduces the fundamental mathematical tools necessary for the study of individual circuits and signals, this course broadens the applications to interconnected networks of filters, plants, and signal sources. Concepts such as stability and stabilization via feedback are important for design work in controllers, communications systems, and power systems. The study of signals and systems in discrete-time prepares the students for modern computer implementations, digital filtering, and numerical methods.
Required for all EE majors; Technical elective for CPE majors. Typically offered: Fall, Spring, Summer II. Program Area: Systems/Controls.
Prerequisites: C- or better in 2704.
This course requires the students to be familiar with the analysis tools (specifically, transform methods and frequency response) taught in EE 2704, Signals and Systems. EE 2704 is therefore a prerequisite for this course.
