AC 2007-1924: FIXED-POINT DSP IMPLEMENTATION: ADVANCED SIGNAL PROCESSING TOPICS AND CONCEPTUAL LEARNING

In this paper a description of a unique fixed point systems course, including a list of topics, a description of labs, and a discussion of the focus on a course project. The course has run four times using simulation environments to promote analysis and visualization. The content of the course has made it apparent that there are numerous linkages to advanced signal processing topics, and these are described. The course has also led to the initiation of an educational experiment using the Signals and Systems Concept Inventory (SSCI) to measure how two very different electives affect student understanding of basic concepts. The experiment compares the fixed point course which is very lab oriented, to a theoretical elective. Preliminary results are described. Work to develop a course text and lab materials is described as part of an effort to promote the adoption of fixed point material widely in electrical and computer engineering curricula.
