Fourier Series Concept Visualization Tools
 |
Chris Long |
For many students the concepts associated with Fourier series can be difficult to comprehend. Two of those concepts are the principle of superposition and the relationship between the time and frequency domains. At Purdue South Bend, Professor Gene Harding and undergraduate student Chris Long worked together using MATLAB to create a pair of visualization tools for illustrating these concepts. Chris did a great job developing these tools, which were used for the first time in ECET207 during the fall 2007 semester. They were subsequently adopted by the main campus and a local community college.
Their paper about the tools, "A Graphical Teaching Aid to Illustrate Fourier Harmonics," was published in the fall 2007 edition of the Technology Interface. (From the fall 2007 edition page, scroll down to the paper via the contents on the left.) This article provides more detail about the two tools, why they were started, and how they fit into Purdue's ECET program.
