Abstract

THE AUDIO SYSTEM COMPRISES A CIRCUIT ( 12 ) FOR PRECESSING AN AUDIO SIGNAL, WHICH CIRCUIT ( 12 ) COMPRISES AN INPUT ( 20 ) FOR RECEIVING THE AUDIO SIGNAL AND AN OUTPUT ( 26 ) FOR SUPPLYING AN OUTPUT SIGNAL. THE CIRCUIT ( 12 ) FURTHER INCLUDES A HARMONICS GENERATOR ( 22 ) COUPLED TO THE INPUT ( 20 ) FOR GENERATING HARMONICS OF THE AUDIO SIGNAL AND ADDING MEANS ( 24 ) COUPLED TO THE INPUT ( 20 ) AS WELL AS TO THE HARMONICS GENERATOR ( 22 ) FOR SUPPLYING A SUM OF THE AUDIO SIGNAL AND THE GENERATED HARMONICS TO THE OUTPUT ( 26 ). THE HARMONICS GENERATOR ( 22 ) COMPRISES AN INTEGRATOR ( 34 ) FOR INTEGRATING THE AUDIO SIGNAL AND, COUPLED THERETO, RESETTING MEANS ( 36 ) FOR RESETTING THE INTEGRATOR ( 34 ) AT RESETTING TIMES.
