Introduction : Time-Frequency Analysis

Introduction : Time-Frequency Analysis. HHT, Wigner-Ville and Wavelet. Motivations. The frequency and energy level of data from real world phenomena are seldom constant. For example our speech, music, weather and climate are highly variable. Traditional frequency analysis is inadequate.
