Abstract :
In this paper, an educational software tool on adaptive filters is presented. The simulation software is written in Java and provides an interactive environment that allows students to investigate and understand adaptive filters. The program exposes students to the concepts and applications of adaptive filters with special emphasis on convergence properties. The different adaptive algorithms that are implemented include LMS, NLMS, BLMS, IIR-LMS and IIR-SHARF. A frequency response visualization module was also developed to observe the magnitude and phase response for the corresponding pole-zero placement in the z-domain. This software tool supports an online software laboratory in the digital signal processing class. The paper also provides examples of possible laboratory exercises.
