Terrestrial Natural and Man-made Electromagnetic Noise
The terrestrial environment is continuously exposed to electromagnetic radiations which set up a “background” electromagnetic noise. For what concerns electromagnetic waves in the Non Ionizing Radiation band (NIR), i.e. for frequencies lower than 300 GHz, the background can have a natural or an artificial origin. In the first case electromagnetic radiations have generally an atmospheric or a co...

متن کاملNatural and man-made terrestrial electromagnetic noise: an outlook
Natural electromagnetic noise sources existing since the origin of the Earth may be influencing the evolution of living systems. Understanding how this background noise is generated and distributed and how it interacts with living systems, can contribute to the general knowledge of life on Earth. In this review we consider the different frequency ranges, starting from the lowest frequencies gen...
متن کاملEffect of Natural Background Noise and Man-Made Noise on Automated Frog Calls Identification System
Frog identification based on their calls becomes important for biological research and environmental monitoring. However, identifying particular frog calls becomes challenging particularly when the frog calls are interrupted with noises either in natural background noise or man-made noise. Hence, an automatic identification frog call system that robust in noisy environment has been proposed in ...
متن کاملMan-Made Noise Evaluation for Cryogenic Receiver Front-End
This paper presents measured results of manmade noise impact on an cryogenic receiver front-end (CRFE) in urban and suburban areas in the 2-GHz band with amplitude probability distribution (APD). The CRFE comprises a high-temperature superconducting filter, cryogenically-cooled low-noise amplifier, and highly-reliable cryostat. The CRFE is expected to be an effective and practical approach to a...
