An Application of the DWT in Seismic Data Analysis
Seismicc signals consist of several typically short energy bursts, called phases, exhibiting several patterns in terms of dominant frequency, amplitude and polarisation. We present a fast algorithm to detect the so-called S-phase in a three-component seismic signal. This new approach combines traditional S-phase detection methods and the discrete wavelet transform.
