Abstract：This paper, taking a view of engineering application and based on the asymp-lotics of signals, analyses practical algorithms and features and limitations in practice of three signal demodulation methods: Hilbert transform method, wavelet based multi-scales method, and asymptotic wavelet ridge extraction method. The advantage and practice problem of the asymptotic wavelet analysis approach, in obtaining the amplitude and frequency modulating information simultaneously, are illustrated with an authentic example of structure vibration analysis.
