Popis: This paper reviews the methods of correcting the frequency response of short-period seismometers and geophones, i.e., the multiplication of the transfer sensor functions by the transfer function of the secondorder correction filter and the provision of a considerable attenuation in the oscillating system (h = 5–10) followed by correcting the frequency response with the first-order filter. The correction device circuit developed by the authors for expanding the frequency range of the GS-20DX geophone has been described. The proposed method has been proved to be effective according to the laboratory tests of the geophone with the frequency response correction according to this circuit.
