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.
