Checking the quality of restoration in the frequency domain of CDSN broad-band seismograms using modern control engineering

  • Published:

Abstract

Incorrect results including false low frequency components may appear during the recovery of ground motion in the frequency domain. In order to check the quality of restoration in the frequency domain of CDSN broad-band seismograms, a digital model of the seismograph systems, based on modern control engineering, is presented and improvement of the method of restoration in the frequency domain is described. Examples shown in this paper demonstrate the effectiveness of the proposed approach in improving the restoration of true ground motion.
