Title (EN) METHOD AND APPARATUS FOR OUTPUTTING AN AUDIO SIGNAL
(FR) PROCÉDÉ ET APPAREIL D'ÉMISSION D'UN SIGNAL AUDIO
Abstract: front page image
(EN)An apparatus for outputting an audio signal with improved sound quality is provided. The apparatus includes a modulation and amplification unit for pulse modulation and switching amplification of an input audio signal and generating an amplified signal which corresponds to the input audio signal; and a vacuum tube amplification unit for inputting a vacuum tube signal generated by attenuating the amplified signal and adding harmonics of a vacuum tube to the amplified signal, to the modulation and amplification unit to provide a mellow sound.
(FR)L'invention concerne un appareil d'émission d'un signal audio ayant une qualité sonore améliorée. L'appareil comprend une unité de modulation et d'amplification pour effectuer une modulation par impulsions et une amplification de commutation d'un signal audio d'entrée et générer un signal amplifié qui correspond au signal audio d'entrée ; et une unité d'amplification de tube à vide pour entrer un signal de tube à vide généré par atténuation du signal amplifié et ajout d'harmoniques d'un tube à vide au signal amplifié, dans l'unité de modulation et d'amplification pour fournir un son doux.
