DECOMPOSITION AND ANALYSIS OF NON-STATIONARY DYNAMIC SIGNALS USING THE HILBERT TRANSFORM

摘要

This paper describes a new technique, called the Hilbert Vibration Decomposition method, dedicated to decomposition of non-stationary wideband dynamic signals. Using the Hilbert transform in the time domain, we extract a number of elementary oscillating components of the initial signal, who's both the instantaneous frequency and envelope can vary in time. Modeling examples of decomposition of non-stationary signals are included.
