                                 DECISION ON APPEAL                                   
               This is a decision on the appeal from the final rejection of           
          claims 2-8, which are all of the claims pending in the present              
          application.  Claim 1 has been canceled.  An amendment filed                
          January 19, 2000 after final rejection was denied entry by the              
          Examiner.                                                                   
               The claimed invention relates to a method for synthesizing             
          music and speech sound signals using sinusoidal modeling.  More             
          particularly, a quadratic phase model approach is provided in               
          which polynomial coefficients are determined by least-square
