Abstract
As an example of the application of spectral analysis of a random process in applied geophysics, we will discuss here the analysis of magnetotelluric data. The natural magnetic and electric fields at the surface of the Earth—covering a large range of frequencies—depend on the electrical conductivity in the ground. High-frequency fields are affected by the electrical conductivity of near-surface rocks, while fields with lower frequencies are influenced by deeper layers.
