Time frequency based signal processing for modal parametric identification

Abstract

Time frequency based signal processing is a popular technique for output only operational modal analysis OMA These techniques are mostly based on either Hilbert transform HT or wavelet transform WT besides other time frequency tools which are less popular among the researcher and engineers Diferent Hilbert transform based techniques are empirical mode decomposition EMD or Hilbert Huang transform HHT ensemble empirical mode decomposition EEMD analytic mode decomposition AMD and newline newline
