Various time-series decomposition techniques, including wavelet transform, singular
spectrum analysis, empirical mode decomposition and independent component analysis …

We propose a time-frequency representation based on the ridges of the continuous chirplet
transform to identify both fast transients and components with well-defined instantaneous …

A new method is proposed in this article for fast-varying AM–FM components extraction.
There are two prominent characteristics in this method. Firstly, a new evaluation method for …

The time-varying frequency structure of musical signals have been analyzed using wavelets
by either extracting the instantaneous frequency of signals or building features from the …

The system modelling and the circuit implementation of the nonlinear circuits using the
wavelet domain techniques has been accomplished in this study. When the time–frequency …

The energy of the multi-component nonstationary signals is distributed over the time-
frequency plane. It might be necessary to separate signal components in time-frequency …
