Abstract
The work is devoted to the practical aspect of separation of pulse-type signals of lithospheric origin in the recorded electromagnetic field by their shape. Experiments on registration of electromagnetic field signals in a wide frequency range have been carried out. In the frequency range from 5 to 20 kHz, pulses consistent with the generalized shape of the pulse of lithospheric origin were detected. Special hardware and software was developed for registration and further processing of electromagnetic field signals in the kilohertz range. With its help, prototypes of pulses of lithospheric origin were identified. An algorithm was proposed and tested, which makes it possible to automatically select pulses similar to the prototype from the entire set of observed data. Field experiments were carried out to isolate pulses of electromagnetic field of lithospheric origin and to determine their energy and quantitative characteristics. Daily variations of the average energy and activity of electromagnetic field pulses of lithospheric origin are revealed.
