“…It's necessary to emphasize that calculating of the Q-factor of a particular contour is a task depending on various parameters [5][6][7][8][9][10]. In practice, it's possible to measure the Q-factor using a special device, so-called Q-factor meter.…”

For a noise-reduction filter, the parameters of the manufactured device often do not fit the expected parameters during development, what is caused by the spread of the parameters of the electronic components or their parasitic parameters, as well as due to the presence of its own capacitance and inductance of the frequency response assembly. In this article, the influence of parasitic parameters of components and fasteners on the filter frequency response is considered. Utilizing the electronic simulator software, the filter parameters were modeled in the frequency range from 10 kHz to 1 GHz. Based on the simulation results, recommendations were given for optimizing the filter mounting elements and changing the inductance of low-frequency chokes.

“…In the spectrogram, you can see beside the Resonance Schumann modes, variations in power line signals and other signals that affect all frequencies about the 500 min, which is due to The magnetic sensors are two magnetic antennas oriented along the main cardinal directions (north-south and east-west). Each sensor is made up of two symmetrical coils that provide balanced differential signals helping to reduce common mode effects [59,60]. An optional notch filter was implemented as part of the measurement system using a double Active cell [61] to attenuate the power signals.…”

For populations that may be affected, the risks of earthquakes and tsunamis are a major concern worldwide. Therefore, early detection of an event of this type in good time is of the highest priority. The observatories that are capable of detecting Extremely Low Frequency (ELF) waves (<300 Hz) today represent a breakthrough in the early detection and study of such phenomena. In this work, all earthquakes with tsunami associated in history and all existing ELF wave observatories currently located worldwide are represented. It was also noticed how the southern hemisphere lacks coverage in this matter. In this work, the most suitable locations are proposed to cover these geographical areas. Also, ELF data processed obtained from the observatory of the University of Almeria in Calar Alto, Spain are shown. This is a contribution to help protect against natural disasters such as those caused by earthquakes and tsunamis.

“…These signals have also been studied as precursor elements of seismic events, due to the variability of SR records in the presence of earthquakes [20], being a topic widely researched in recent decades [21]. The diverse applicability of these signals, together with the complexity of their detection [22] and the need to develop specific equipment for the measurements [23], have been widely developed research topics in recent years and even today they are considered topics of interest as they are not efficiently resolved [24].…”

This paper describes the characteristics of contributions made by researchers worldwide in the field of ELF (extremely low frequency) waves from 1957 to 2019. The data were collected through the Scopus database and processed with analytical and bibliometric techniques. The selection of the keywords is an essential step, because ELF has a very different meaning in some areas of medicine, where it is associated with a gene. A total of 12,436 documents were worked on in 12 thematic communities according to their collaborative relationships between authors and documents. Studies included authors publishing in the different thematic areas and the country where the USA stands first with more researchers in this theme than China and Japan. Documents were analyzed from the temporal perspective, their overall contribution, means of publication, and the language of the publication. Research requires extra effort and multidisciplinary collaboration to improve the knowledge, the application, and influence of these fields.
