Abstract
We analyze waveforms of natural extremely low frequency (ELF) transient events. It is shown that model waveforms are observed with the wide band receiver at places with exclusively low level of industrial radio noise. In conclusion we describe extracting of natural ELF transient signal from under the industrial noise by using algorithm of singular spectral analysis.
KEY WORDS:Schumann resonance, Q-bursts, principal components
