A Synthetic Solution for Identification and Extraction of the Effective Microseismic Wave Component Using Decomposition on Time, Frequency, and Wavelet Coefficient Domains

<div>Decomposition structure in the frequency domain of a wave via the wavelet packet transform. The original wave at the basic level passes through two complementary filters (low-pass and high-pass) and emerges as two subwaves A<sub>1</sub> and D<sub>1</sub>. Subwave decomposition at the sublevel follows the same rules.</div>
