An Experience, Using Software Based Tools for Teaching and Learning Mathematically Intensive Signal Processing Theory Concepts

Abstract

The paper emphasizes the need for teaching and learning mathematically intensive theory subjects using very powerful software tools. Under Electrical Engineering discipline, there are subjects like Signals & systems, Control Systems, Digital Signal/Image Processing etc. where teachers need to spend a considerable amount of time in classroom, teaching the mathematical concepts, ending up with very low level of learning by students. Learners find it very complex and unrelated as mere lecturing doesn't help them in effective interpretation of the information conveyed. There are many such software tools available nowadays having a powerful graphical data flow programming environment with a rich set of library functions and tools sets in simulation and real time mode. Such tools can simplify the teaching and learning of subjects with intense mathematical background in lesser time for the students from non-electronics stream. Here we present the efforts of teachers in learning and teaching, Signal acquisition, processing and analysis techniques for sixth semester students of Automation and Robotics in a much effective manner, using LabVIEW tool. The processed data can be presented from the tool using measurement graphs, indicators, animations, tabulated data, automated calculations, physical interpretation, visualization effects etc., thus enabling the learner with better understanding of concepts. Here we present the results of extensive use of tool to teach and learn different signal processing and analysis techniques used for biomedical signals along with the experience shared by teachers and students undergoing the activity. Course projects implemented by students after undergoing the proposed activity helped teachers to know the accelerated process of learning of the basic concepts of signal processing by students.
