What is claimed is:     1. A machine-implemented method of signal processing, comprising the steps of:
  • receiving an input signal representing a source of vibration;
  • wavelet-transformingthe input signal; and
  • extracting features of said input signal by performing a Mellin transform on the output of said wavelet-transforming step in synchrony with periodicity or pseudo-periodicity of said input signal.
