Trustworthiness measurement

• Relatively large peak interferes others but not very much being affected --> high credibility score
• Peak situated relatively far from others is less interfered --> high credibility score

  

  where the normalized amplitude of each component

  

  The function g is the envelope approximation of the transformed processing window e.g.
  

  

  
  
  
  

  give a close approximation to sinc envelope for rectangle window. We then decide that the partial is weak in relation to a threshold
