Translating Information from Graphs into Graphs: Signals Processing
Margret A. Hjalmarson, Kathleen E. Wage, and John R. Buck
Abstract
Students studying signals and systems processing participated in
clinical interviews related to their understanding of fundamental
concepts in the discipline. This includes the interpretation of
graphical representations of signals and functions. Preliminary
analysis indicates that students with understanding of fundamental
structures in signal processing (e.g., frequency, magnitude) can
organize information from multiple graphs simultaneously to make
projections about a system of signals. Mathematically, they need to be
able to organize and interpret multiple representations in order to
make predictions about a system.
