TEACHING DIGITAL SIGNAL PROCESSING USING SKITS A CASE STUDY
Digital Signal Processing (DSP) involves acquiring real time signals, digitizing them and mathematically manipulate to extract useful information. Traditionally DSP has been taught in engineering colleges using simulation software to develop interest among students. Connections between abstract signal processing theory and real world signal processing system design are difficult to illustrate in a packed undergraduate curriculum. We have proposed usage of skits for explaining concepts and employing students to act and interactive audiovisual aids as tools for learning DSP. Based on the pretest and posttest scores, we found that group using Skits and audiovisual tools got better scores than group using only audiovisual tools in their ability to understand concepts by applying to simple real world examples. Hence the usage of these interactive teaching aids helps in increase of student's interest to learn, visualize and understand key DSP concepts.
