Аnnotation: Low-frequency deconvolution of precise digital records of seismic and industrial vibrations allows significant expansion of the frequency range of electrodynamic geophone, limited only by the deconvolution noise which is represented by increased instrumental noise. In the paper a theoretical deconvolution noise assessment is presented, the assessment depends on receiver natural frequency decrease rate and on the initial instrumental noise. A method and a simple facility for the experimental deconvolution quality evaluation are proposed. The real data example of 100-times receiver virtual natural frequency decrease is shown.
