• Decomposition with a priori basis produces
  components with wave form similar to the basis
  adopted.
• Decomposition with adaptive basis produces
  components with wave form retaining the physical
  properties of the underlying processes.
• Adaptive basis could be used as filters that
  would preserve the intrinsic properties of the
  data.
