Résumé

The educational software tool Dosher is presented for the analysis of super heterodyne demodulation of signals, being applicable for enhancing the understanding and learning of the principles of communication theory mainly in Telecommunication engineering. This tool is intended to assist students (high school, undergraduate as well as Ph.D.) about the knowledge of the so-called super heterodyne receivers. Thanks to Dosher (DOwn Super HEterodyne Receiver), students will be able to check how the demodulation process from radiofrequency band down to base band takes place in the frequency domain. Furthermore, they will be able to fully design the receiver, analyze the unwanted effect called Image Frequency, or create reports compiling the expected results and design obtained. To the best of the authors’ knowledge, neither professional nor educational software alternatives for the learning of this field of communication theory have been proposed so far. Dosher is a user-friendly teaching-oriented software developed with MATLAB that successfully combines the use of signal graphical representation with accurate results at any stage of the receiver.
