... multicomponent signals, the choice of the TFD plays a crucial role due to the presence of the unwanted cross-terms which disturb the signal representation in the (t, f ) domain. The best-known TFD of a monocomponent ... stops once the energy remaining in the TFD is smaller than the threshold value  d defined as a fraction of the signal total energy. The secon...
