The participants of this workshop will be exposed to the utility of the Java-DSP education software in multidisciplinary signal and data analysis applications. The session will be interactive and participants will use and assess an exercise that involves step-by-step online simulations using Java-DSP. Examples of prepackaged online laboratory exercises generated in 2010 that can be disseminated in certain types of data related courses will also be presented. A newly developed interactive learning environment, involving online quiz synchronized with multiple JavaDSP simulations, will be of special interest to the participants. Apart from basic modules that will be useful for DSP courses, new modules in music and audio signal processing, wireless communications, and power systems will also be demonstrated. The workshop will be useful to instructors and practitioners with interests in signals and systems, DSP, data analysis for earth systems and geology, signal analysis for music courses and other applications.
