Linear signals and systems is a core subject in the undergraduate electrical and computer engineering curriculum. The Signals and Systems Concept Inventory (SSCI) is a twenty-five-question, multiple-choice exam designed to assess students' understanding of fundamental concepts in this subject. There are separate versions of the SSCI exam for continuous-time (CT-SSCI) and discrete-time (DT-SSCI) material. John Buck (University of Massachusetts Dartmouth) and Kathleen Wage (George Mason University) are the principal developers of the SSCI. For more information on the SSCI, see the project homepage: signals-and-systems.org.
The Foundation Coalition, supported by a large grant from the National Science Foundation, funded the initial development of the SSCI. GMU funding for this project came from Foundation Coalition subcontractors.
