          Judges.                                                                     
          FLEMING, Administrative Patent Judge.                                       

                                 DECISION ON APPEAL                                   
               This is a decision on appeal from the final rejection of               
          claims 1 and 3-18, all the claims pending in the present                    
          application.  Claims 2, 19 and 20 have been cancelled.                      
               The invention relates generally to a sampled amplitude read            
          channel for reading discrete time sample values (Xk) (25)                   
          generated by sampling an analog read signal (19) from a read head           
          positioned over a magnetic read medium (18).  See figure 3, and
