Short introduction to J-DSP

 

 

At Arizona State University (ASU) and other major metropolitan universities, DSP-related courses are well attended by distance learning students. In order to provide on-line laboratory experiences to distance learners the ASU Multidisciplinary Initiative on Distance Learning (MIDL) laboratory developed and tested successfully an exemplary laboratory prototype tool, called Java-DSP (J-DSP). This simulation environment enables students to establish and execute DSP simulations from any computer equipped with a browser.

J-DSP, a distance learning paradigm, has a rich suite of signal processing functionalities. All functions in J-DSP appear as graphical blocks that are divided into groups according to their functionality. Selecting and establishing individual blocks can be done by a drag-and-drop-process. Each block is linked to a signal processing function. Figure 1 shows the J-DSP editor's user interface. By connecting blocks together, a variety of DSP systems can be simulated. Blocks parameters can be edited through dialog windows, allowing the user to change the corresponding function’s parameters to desired values and/or to view results. They can easily be manipulated (i.e. edit, move, delete and connect) within the specified drawing area. System execution is dynamic, which means that any change at any point of a system will automatically take effect in all related blocks. Any number of block windows can be left open to enable viewing results at more than one point in the system.

The remainder of this short J-DSP tutorial provides further information on J-DSP. Some documentation that follows requires Adobe Reader that you can install from Adobe's web site. Also note that if you experience problems with loading J-DSP, these can be solved simply by installing the latest Java virtual machine from Sun.
