THE JAVA-DSP PHASE 3 PROJECT; AN INTERDISCIPLINARY MULTI-UNIVERSITY EFFORT 1. Introduction Java-Digital Signal Processing (J-DSP) is a web-based, platform-independent, visual programming environment that enables users to perform online signal processing calculations and simulations1. It is based on an object-oriented programming environment that allows students and practitioners to run simulations over the Internet. Simulations can be performed in the intuitive graphical interface of J-DSP by placing and connecting “blocks” to establish signal and data flow. Students can also visualize the results interactively in the simulation environment. Original J-DSP functionality included algorithms for signal processing2, imaging3, controls4, time-frequency analysis5 and communications applications6.

This paper presents our plans in the NSF CCLI Phase 3 project which are aimed at developing, disseminating and assessing several new J-DSP capabilities. By engaging a total of seven universities in the development and assessment of software and course content, we extend the utility of J-DSP to several disciplines including Electrical Engineering, Earth Sciences, Biomedical Engineering, Power Engineering, and Arts and Media. The key outcomes of the CCLI phase 2 project included a) upgrades to the J-DSP GUI, b) extensions in the signal processing functionality of J-DSP, c) on-line laboratory exercise development, and d) dissemination and assessment and a pilot test of a new multi-site laboratory concept that allows students in the five universities to run real time distributed on-line simulations. Results of the Phase 2 project have been published mainly for Electrical Engineering courses and applications1-6. In addition, a book that uses J-DSP for online laboratory exercises has been published7 and is used in two courses at Arizona State University. The phase 3 multidisciplinary NSF CCLI project is a collaborative project involving Arizona State University (ASU), Johns Hopkins University (JHU), University of Washington Bothell (UWB), and Prairie View A&M University (PVAMU). In addition to these four institutions that are a part of the formal NSF research collaborative structure, the project also involves sponsored partnerships with Rose- Hulman Institute of Technology (RHIT), University of New Mexico (UNM), and University of Cyprus (UCY). Other partnerships through the collaborating institutions have also been organized with the University of Texas at Austin and the University of Padova.
