Abstract

Arizona State University (ASU) has developed an on-line DSP laboratory that is based on an object-oriented Java tool called Java Digital Signal Processing (J-DSP). J-DSP is currently being used in a senior-level DSP course at ASU. J-DSP has a rich suite of signal processing functions that facilitate interactive on-line simulations of modern statistical signal and spectral analysis algorithms, filter design tools, QMF banks, and speech analysis. In this paper, we present a series of significant functionality extensions of J-DSP enabling on-line laboratories in the system-related areas of Communications, Image Processing, and Controls. The extensions in communications are presented in some detail. In addition to these important functionality extensions, we present enhancements in the infrastructure of J-DSP that provide embedded scripting capabilities. Scripts enable easy creation and seamless integration of interactive animations in DSP web content. The latter is very important for instructor creating their own DSP-related web courses as it provides for user-friendly development of interactive visualization modules through the J-DSP applets.
