DSP Instead of Circuits? - Transition to Undergraduate DSP Education at Rose-Hulman W. Padgett, M. Yoder (Rose-Hulman Institute of Tecnology, USA) We assert that digital signal processing (DSP) can and should be taught early (sophomore-junior) in the electrical and computer engineering curricula. This paper looks at the impact this has on the rest of the curriculum, both in electrical and computer engineering and in other engineering curricula. While the early introduction of basic DSP makes it possible to offer better senior electives and graduate courses in DSP, the biggest benefit is the ability to build on DSP core concepts just as we have traditionally built on circuits core concepts in the past. Further, motivational examples in DSP lend themselves to multimedia and are often more familiar to today's students than basic circuits. |

A Java Signal Analysis Tool for Signal Processing Experiments A. Clausen, A. Spanias, A. Xavier, M. Tampi (Arizona State University, USA) In this paper, a program to simulate discrete time linear systems is presented. The software is written as a Java applet and can be accessed on the internet. Object oriented programming allows the user to construct and simulate a variety of systems. The program uses a graphical user interface which is easy to learn and it provides a visualization of the system and signal flow. The software is currently being used at Arizona State University to support an online software laboratory for a senior level digital signal processing (DSP) course. This paper presents our experiences gained by using the program in a class setting and gives examples of possible laboratory problems. |

Visualization of Signal Processing Concepts J. Shaffer, J. Hamaker, J. Picone (Mississippi State University, USA) One of the key difficulties in a Signals and Systems course is the visualization of mathematically complex concepts presented. Thus, there is a need for graphical tools which enhance the students' comprehension of these difficult concepts by allowing interactive learning. In this paper we present a software package to assist in the explanation and visualization of signal processing concepts for an educational environment. We provide a set of Java-based tools for understanding the concepts of convolution, spectral analysis, and pole/zero system response. The wide availability and platform-independence provided by Java make this tool highly portable and easily accessible to a broader audience of students than comparable systems based on Matlab or other commercial software. The software described in this paper is available in the public domain at our website: http://isip.msstate.edu/. |

An Experimental Architecture for Interactive Web-based DSP Education M. Rahkila, M. Karjalainen (Helsinki University of Technology, Finland) This paper describes an experimental architecture for interactive education of DSP in the World Wide Web environment. The architecture is based on a client-server model providing means of distributing resources. The major design goal has been to combine interactivity and computational resources. The architecture itself is open in a sense that it does not specify implementation and it can be used for a variety of applications. Computer Based Education (CBE) of DSP is one area where it can be beneficially applied. An example of implementation for that purpose is presented. With our implementation, special attention has been paid to minimize the requirements of additional software for the user because of educational reasons. Thus only a Java-capable browser and audio support are needed at the user end. |
