Abstract
Signal processing can be a mathematical intense subject and undergraduate students may not be able to appreciate the enormous importance on the applied side of things. Even if the instructor mentions some of the fascinating application areas, it might be difficult for students to attend a laboratory session in which they will have enough time to code a signal processing algorithm and see a big difference when processing data in the frequency domain. In this paper I describe a simple example in which students have an opportunity to develop a theoretical solution to enhance an image and with just a few lines of code run a program that will show a dramatic difference between an original image and the enhanced version. Different fundamental signal processing concepts are reinforced with the laboratory example and its application only requires a computer and signal processing developing software such as Matlab.
