TO IMPROVE THE OPERATION IN THE PRESENCE OF SIGNALS WITH STRONG HARMONIC COMPONENTS (FOR EXAMPLE SIGNALING TONES) A LPC PREDICTION GAIN IS CALCULATED FROM THE INPUT (X (I)) AND A RESIDUAL (Y (I)) OBTAINED FROM THE THAT FOLLOWS THE FILTERING THROUGH A FILTER (105) THAT HAS A COMPLEMENTARY RESPONSE TO THE FREQUENCY SPECTRUM OF THE ENTRY, AND IF THE GAIN EXCEEDS A DEFAULT VALUE, THE UPDATING IS DELETED.
