Murat Tanyel is a professor of engineering at Geneva College. He teaches upper level electrical engineering courses. Prior to teaching at Geneva College, Dr. Tanyel taught at Dordt College in Sioux Center, IA. He started his career at Drexel University where he worked for the Enhanced Educational Experience for Engineering Students (E4) project, setting up and teaching laboratory and hands-on computer experiments for engineering freshmen and sophomores. For one semester, he was also a visiting professor at the United Arab Emirates University in Al-Ain, UAE where he helped set up an innovative introductory engineering curriculum. Dr. Tanyel received his B.S. degree in electrical engineering from Boğaziçi University, Istanbul, Turkey, his M.S. degree in electrical engineering from Bucknell University, Lewisburg, PA and his Ph.D. in biomedical engineering from Drexel University, Philadelphia, PA.

Abstract

Most Digital Signal Processing (DSP) courses rely heavily on MATLAB and/or C, representingthe state of the art in textual programming, for their standard computer tools. We have argued, inprevious papers, that whereas this environment may be efficient in manipulating equations,textual implementation of processes best described by block diagrams loses its intuitivesubstance and have provided examples of LabVIEW implementations that are better leftgraphical. The standard DSP toolkit of LabVIEW is aimed at the practicing engineer/scientistwho needs to process acquired data to reach other ends in contrast to a student whose aim is tolearn about signal processing. LabVIEW’s DSP toolkit is rich with high level algorithms butneeds to be enhanced in order to serve the pedagogical needs of students of DSP. While teachingthis course at a previous institution, I developed many routines to complement the standard DSPtoolkit as I tried to demonstrate basic concepts. Returning to teaching DSP at my new institutionafter a break of 6 years, I have found myself having to revise some of those old tools and havegot excited about new possibilities that LabVIEW has to offer in this field. This paper willreview my past experience and will focus on this additional toolkit that I have developed to makeLabVIEW a better teaching tool in a DSP class. In particular, I will provide detailed descriptionsof classroom activity that takes advantage of LabVIEW’s sound capture and playback routines.The paper will conclude with the results of a focus group discussion with the students of the DSPclass.
