Three Practical Demonstrations In Beem Project

This paper presents three practical examples that have been created in the BEEM (Biomedical and Electrical Engineering Methods) project at RoseHulman Institute of Technology. These examples are used to introduce respectively (1) Construction of a prototype electrocardiogram measurement system, (2) Use of inductance coils to perform as transformers, and (3) Audio signal filter. These demonstrations are easy and inexpensive to implement and perform. They have been used to help students understand the underlying electrical principles in addition to demonstrating measurement techniques and solution options for the topics discussed in related electrical and/or biomedical engineering courses. By the means of demonstrating the realworld applications, they should prove useful in improving students’ learning and interest in electrical engineering principles and applications.
