Earthquake time-frequency analysis using a new compatible wavelet function family

Amir Bazrafshan Moghaddam and Mohammad H. Bagheripour

Abstract

Earthquake records are often analyzed in various earthquake engineering problems, making time-frequency analysis for such records of primary concern. The best tool for such analysis appears to be based on wavelet functions; selection of which is not an easy task and is commonly carried through trial and error process. Furthermore, often a particular wavelet is adopted for analysis of various earthquakes irrespective of record

Key Words

time-frequency analysis; wavelet function; continuous wavelet transform; multi-resolution analysis
