Abstract
The techniques of digital signal processing (DSP) and digital image processing (DIP) have found
a myriad of applications in diverse fields of scientific, commercial, and technical endeavor. DSP and
DIP education needs to cater to a wide spectrum of people from different educational backgrounds.
This paper describes tools and techniques that facilitate a gentle introduction to fascinating concepts in
signal and image processing. Novel LabVIEW and MATLAB based demonstrations are presented, which,
when supplemented with web-based class lectures, help to illustrate the power and beauty of signal and
image processing algorithms. Equipped with informative visualizations and a user-friendly interface, these
modules are currently being used effectively in a classroom environment for teaching DSP and DIP at
The University of Texas at Austin. Most demos use audio and image signals to give students a flavor of
real-world applications of signal and image processing. This paper is also intended to provide a library of
over 50 visualization modules that accentuate the intuitive aspects of DSP algorithms as a free didactic
tool to the broad signal and image processing community.
