The low-frequency deconvolution method makes it possible to convert digital records of electrodynamic seismometers to records of virtual sensors of a similar type, but with a lower natural frequency. The procedure requires only knowledge of the senso

A method of absolute calibration of electrodynamic seismic sensors by single-sensor displacement is theoretically justified. It is shown that the method can be implemented using simple mechanical devices and a recording system. The required mathemati
