Title:
SYSTEMS AND METHODS FOR TUNABLE WAVELET TRANSFORM ANALYSIS OF A SIGNAL
Document Type and Number:
WIPO Patent Application WO/2012/118790
Kind Code:
A3
Abstract:
Methods and systems are disclosed for tuning first and second wavelet functions to resolve at least one component of a signal. A first characteristic frequency corresponding to a first scale band of interest is determined, and a first wavelet function is tuned to the first characteristic frequency in at least a region of a first scale band of interest. A second characteristic frequency corresponding to a second scale band of interest is determined, and a second wavelet function is tuned to the second characteristic frequency in at least a region of the second scale band of interest. A signal is transformed for the first and second wavelet functions using a continuous wavelet transform to create a transform signal, and a scalogram is generated based at least in part on the transformed signal.
