### Course Goals

This is a basic course on linear system theory at the graduate level. Linear system theory is important as a cornerstone of control theory and is also useful in areas such as signal processing. The main goal of the course is to familiarize the student with the concepts, tools, and techniques commonly used in linear system theory. Thus, students will not only learn the fundamental results and constructions of the theory, but will also learn to synthesize these results on their own and to produce similar results using the tools learned. The course is taught at a high level of mathematical rigor, and students are expected to understand results as well as their derivations.

### Course and Topic Prerequisites

Course prerequisites: ENEE 460 or equivalent, MATH463 or equivalent, or permission of instructor.

Topic prerequisites: Vector spaces. Linear systems of algebraic equations and matrix algebra. Elementary differential equations. Routh and Nyquist criteria for stability of linear systems. Laplace transforms and transfer functions of simple scalar systems.
