J-DSP Signed Applet Version

Description: The long awaited J-DSP version with software infrastructure for using actual .wav files along with existing speech and audio functionalities. Functionality for saving and loading J-DSP scripts to and from files is also developed as a part of it. It is developed using the Java Signed Applet Capability and hence poses certain security threats. The user is once again warned about the security threats related to Signed Applet of Java.

J-DSP Communications Version

Description: J-DSP communications functions and laboratory exercises have been developed to support the laboratory portion of the ASU communications elective, EEE455. The functionality developed covers both analog and digital communications. The J-DSP communications laboratories include descriptions of relevant J-DSP functions, lab exercises illustrating the key concepts, and a short quiz that captures the main points of the assignment. The J-DSP communication labs have been assigned in EEE 455 and assessment results have been compiled. Assessment results indicate that the majority of the students responded that the new J-DSP functionality and the associated lab exercises complemented well the theory covered in class and helped them develop intuition on the communications concepts covered in these labs.

J-DSP Multi-Dimensional Signal Processing Version (Image Processing)

Description: Innovative on-line java-based educational DSP software modules were developed to render possible on-line laboratories for two-dimensional digital signal processing. The developed software modules provide on-line 2-D DSP capabilities, including 2D signal generation, 2D FIR filter design & implementation, and 2D transforms. On-line image processing capabilities are also provided, including image restoration and enhancement. In order to illustrate 2D concepts graphically, contour (2D) and perspective (3D) plots have also been implemented and incorporated as part of the developed software tools. Online laboratory exercises have been developed in the aforementioned areas for use in the graduate-level Multidimensional Signal Processing and Image Processing courses at ASU. Statistical and qualitative evaluations prove the effectiveness of the developed on-line 2D DSP software and laboratories in improving the learning experiences of the students.

J-DSP Controls Version

Description: J-DSP Controls Version is a Java-based object-oriented programming environment that was developed at Arizona State University for use in control systems education. This environment enables the simulation of dynamical systems on-line from any computer system equipped with an Internet browser. Its features are primarily aimed to provide an on-line laboratory experience to distance learning students. Combined with a report submission and scoring facility, it integrates interactive examples into web content for education and demonstration purposes.

J-DSP Sensor Motes Version

Description: Distributed wireless sensor networks (WSN) are being proposed for implementing smarter environments for security and other applications. In this project, we present a collection of Java interfaces for the Berkley sensor motes for use in tracking and localization research projects. By integrating the mote interfaces with Java-DSP we can make use of the J-DSP signal processing functions for real-time analysis of the signals acquired from the wireless sensors. Connectivity with the signal processing environment of Java-DSP is seamless and allows the user to program and run sensor signal processing algorithms from remote locations. Extensions of this project are planned for remote control of the motes by handheld devices.

J-DSP DSP Boards Version

Description: Interfaces of DSP hardware with the NSF funded Java-DSP (J-DSP) education software for use in undergraduate signals and systems and DSP classes have been recently made. The interface enables undergraduate students to design and implement algorithms real time on DSP hardware using the user-friendly graphical interface of J-DSP. Simulations involving digital filters and FFTs are first established in the object oriented J-DSP environment. Through the use of a clever software interface, a real-time implementation of the algorithm is activated on the TI DSP Starter Kit C6713. The real-time implementation enables the students to examine the properties of various signal processing algorithms using real-life signals. A simple audio compression scheme that uses the Fast Fourier Transform (FFT) is developed. The hardware–software interaction of J-DSP with the TI DSK is also explained to students; an introduction to the architecture and its peripherals is also part of the learning experience. Pre- and Post- assessment instruments have been developed and administered.

J-DSP Demos Version

Description: J-DSP Version where the script in a .html file opens up in the existing J-DSP Window, instead of creating another window. In case J-DSP is not already opened, it opens a new J-DSP window. This infrastructure has been developed using java sockets.
