Abstract
In this paper, we present educational filter design tools used in the signals and systems course. A graphical-user-interface (GUI) for filter design using the frequency-sampling method has been developed and embedded as a module in the Java-DSP (J-DSP) editor. Three realizations are presented: the non-recursive, non-recursive using least-squares, and recursive. The paper describes several laboratory exercises that involve interactive filter design using the 'Freq. Samp' block. The performance of the frequency sampling method is compared against the performance of the Kaiser and Parks-McClellan algorithms. The exercises have been used at Arizona State University in the signals and systems course. Pre- and post- assessment quizzes have been assigned and results have been compiled to evaluate the learning attributed specifically to the J-DSP software and exercises.
