Claim 22:
23. The device according to claim 19, wherein the wavelet coefficients are standardized by the following formula:, T
    
     f
     ,
     
      Z
      
       H
       0
      
     
    
    i
   
   [
   
    n
    ,
    m
   
   ]
  
  =
  
   
    
     
      T
      f
      i
     
     [
     
      n
      ,
      m
     
     ]
    
    -
    
     μ
     [
     m
     ]
    
   
   
    σ
    [
    m
    ], where
n is a time index and m is a frequency index,
Tfi,ZH0 and Tfi[n,m] are real or imaginary coefficient for n and m after and before standardization,
μ[m] and σ[m] correspond to a mean and a standard deviation of an estimated Gaussian at a frequency of the frequency index m.
