[PDF][PDF] Detection of P-and S-wave arrival times using the discrete wavelet transform in real seismograms
In this study, a novel solution based on discrete wavelet transform is introduced to determine
P-and S-wave arrival times. An algorithm is developed based on changes in frequencies
and energy in high frequency bands. Firstly, the earthquake seismogram is divided into a
series of windows of 256 samples in length, neighboring windows overlapping by 128
samples. Next, each window is decomposed to its high frequency and low frequency
components using discrete wavelet transforms. After that, energies of these components are …
