Abstract:  Theory and experimentation are both complementary in sciences. Where the former builds up a formal framework, the latter helps humans to develop their intuition. Hard-printed books are great supports for theorems and formulas repositories, but stay desperately static when providing examples. This paper presents some directions towards a framework for digital publishing, distance learning and computer-aided teaching. Preliminary results were presented in [2]. The Interactive Digital Signal Processing (DSP) Book is built in this framework and provides a concrete example to the reader. The book, reachable at http://lcavwww.ep.ch /DSPBook, is used as a digital support for a course taught by our lab to a third year undergraduate class in Electrical Engineering. INTRODUCTION Traditionally, both in teaching and research, theory and experimentation were the two complementary approaches to achieve progress. Currently, computer experimentation plays an increasingly important role. Therefore, i...
