Abstract
Java Digital Signal Processing (J-DSP +) is a Java-based objectoriented programming environment that was developed at Arizona State University (ASU) for use in undergraduate- and graduate-level engineering classes. J-DSP is written as a platform-independent Java applet that resides on the web and is thereby accessible by all students using a web browser. In this paper, we describe an innovative software extension to J-DSP, called 2D J-DSP, to accommodate on-line laboratories for two dimensional digital signal processing. Two-D DSP capabilities in J-DSP include: 2D signal generation, 2D FIR filter design & implementation, and 2D transforms. Image processing capabilities include: Image Restoration and Enhancement. In order to illustrate 2D concepts graphically, contour (2D) and perspective (3D) plots have been incorporated in 2D J-DSP. On-line laboratory exercises have been developed in the aforementioned areas for use in the graduate-level Multidimensional Signal Processing and Image Processing courses at ASU, and are posted on the web site (http://id5p.asu.edu). Statistical and qualitative evaluations that assess the learning experiences of the students that use 2D J-DSP are also presented.
