Wavelet Transform: Presentation of Time-Frequency Decomposition for a Mining Induced Seismic Event

摘要

In this contribution, a record of mining induced seismic event is used to demonstrate effects of the wavelet transform. The time-frequency decomposition of wavelet coefficients is conceived as a successive decomposition of the signal on particular levels of wavelet frequencies. The main results are shown graphically in figures that represent the decomposition of record of the seismic event induced by a quarry blast in the Chomutov region.
