Empirical mode decomposition for adaptive am fm analysis of speech

Abstract

This thesis investigates and endorses a non linear and non stationary data analysis technique called Empirical Mode Decomposition EMD as an alternative to the conventional methods of speech analysis This thesis commences with a study of EMD as an adaptive AM FM analysis technique its characteristics and its advanced variants used to curtail mode mixing an inherent but undesirable phenomenon specific to EMD Based on this study this thesis first proposes a modified EMD algorithm denote
