EE230, Signals and Systems, introduces the Fourier and Laplace transforms as methods to model and analyze
continuous-time linear systems (primarily first and second-order circuits) in the frequency domain. Parallels
between the time and frequency domains are discussed, and sampling and filter design issues are developed. The course
makes extensive use of Matlab as a computational and visualization tool. Labs reinforce theory and develop hardware
skills. Prerequisites: EE 223 and MA311. (3 lecture hours)

Lecture Schedule
In the following table, the readings and homework are assigned on the day listed and due on the following lesson. The readings are taken from
the custom-printed class textbook unless otherwise noted.
Some problem sets are downloaded below and completed by the
student on engineering graph paper. Others are links to online electronically-graded problems that are due 10 minutes prior to
the start of class - make sure you have saved your work by then.
You already registered with Connect system in the fall EE223
semester
here
which grants you access to the online text and problems.
If you bought the EE223 text through the bookstore, the last
page of the text gives code to
register with Connect good for 2 semesters; if you purchased the text elsewhere
you must buy Connect access directly through the link to
complete the E-Assignments.
