Regularized Deconvolution of Local Short-Period Seismograms in the Wavelet Packet Domain (2008)
J. Rosa-herranz, J. Giner, S. Molina, F. Botella
Abstract Short-period seismographs of the vertical component have a frequency response similar to a bandpass filter with a low cutoff frequency around 1 Hz. This instrument’s response distorts in...
De-noising of short period seismograms by wavelet packet transform (2003)
J. Rosa-herranz, J. Giner, S. Molina, F. Botella
Abstract The wavelet packet transform gives information in both the time and frequency domains, and it is very useful for describing nonstationary signals like seismograms. Moreover, this structure...
