Digital Signal Processing and Bioinstrumentation using LabVIEW, the new ELVIS Benchtop Platform, and BIOPAC
Students interested in biomedical instrumentation and the signal processing of biomed- ical signals are sometimes at a disadvantage compared to a traditional electrical engineering student. They often have not had as many courses or as rigorous a treatment of many of the foundational topics important to instrumentation and signal processing. To help rectify this situation, we created a two-course bioengineering sequence that makes extensive use of LabVIEW and ELVIS from National Instruments and various BIOPAC products. This pa- per includes a description of the courses, the associated lab exercises, student responses, and recommendations.
A new, two-course sequence in biomedically-oriented digital signal processing and bioinstrumen- tation has been created by the Electrical and Computer Engineering Department at the University of Wyoming. While bioengineering students have shown a high degree of interest in these top- ics, their background and preparation in traditional signal processing and instrumentation is often not as strong as a traditional electrical engineering student. For example, electrical engineering students take courses in circuit theory, electronics, linear systems, and digital signal processing, all of which apply in some way to bioinstrumentation and biosignal processing. Furthermore, most bioinstrumentation and biosignal processing textbooks assume prior knowledge of these ar- eas.1–7 Yet there are many students who wish to learn more about bioinstrumentation and biosignal processing who either have not taken all these foundational courses or do not feel well prepared in these areas. To meet this pedagogical challenge, the authors have incorporated a large number of demonstrations and laboratory exercises into these courses, based upon our experience that this greatly aids learning.8–12 We take advantage of a new and highly ﬂexible tool for educators: the new ELVIS benchtop platform combined with the latest version of LabVIEW, both now available from National Instruments (www.ni.com). In addition, the authors integrated various BIOPAC products (available from BIOPAC Systems, Inc., www.biopac.com) with ELVIS in a way not seen before. The results of using this approach have been highly successful.
ELVIS stands for Educational Laboratory Virtual Instrumentation Suite. It provides an integrated benchtop platform for prototyping, design, testing, measurement, and data analysis with multi- instrument functionality. When coupled with LabVIEW software, a standard data acquisition card,
