Radio definida por software y docencia en línea: experiencia en el Grado en Ingeniería Telemática
[EN] Devices based on software defined radio have been used in the last 6 years as motivating elements in the laboratory practices of digital communications courses at the Degree in Telematics Engineering of the University of Valencia. However, the development of these practices requires giving access to some hardware devices that are physically located in the laboratories of the School of Engineering. In this contribution, taking into account the current situation of hybrid learning and a possible transition to remote learning due to the COVID-19 pandemic, a system that allows the remote interaction with the software defined radio devices is proposed. This remote access system, in addition t…
Graphical Schemes Designed to Display and Study the Long-term Variations of Schumann Resonance
This work proposes and illustrates a graphical approach aimed at studying a wide range of features of the ELF horizontal magnetic field signal recorded at the Sierra Nevada station (Spain). In addition to the traditional long-term variations in the parameters of the first three Schumann resonances (their amplitudes, central frequencies and widths), many other properties such as the saturations of the magnetometers, anomalous values for the parameters or spectra with any kind of particularities are taken into consideration in this work. These features can provide us with complementary information about the long-term variation of Schumann resonances, give an estimation of the extent up to whi…
