• Resumen

  • This communication describes an educational project that has been set-up in order to familiarize the students with the new trends in the field of the new technologies during the latest years. In this project, compelling reasons will be offered to the students in order to facilitate their own approaching to technological realities, like for example computers equipped with analogical-todigital devices, as well as to realize new concepts, like the management of information in realtime or the computation of mathematical operations by using electronic devices. This project is based on the necessity of innovate the current educational resources and to adapt them to the new technologies. Specifically, the project focuses in the development of an experiment for the Physics laboratory of 2nd degree of Bachillerato, which exposes some properties of time-variable electrical signals by using very simple circuits (RC circuit), but still, allowing a very detailed and an interesting analysis of them. Moreover, it will be shown that it is even possible to manipulate physically the electrical signals in order to operate several mathematical transformations like derivative or integral operations
