  • Method and apparatus for outputting audio signal
    Patent number: 7298204
    Abstract: A method and an apparatus for outputting an audio signal are provided. The apparatus includes a power source; a compensator for compensating an input signal by adding the input signal to an offset value reciprocally proportional to a source voltage; a pulse width modulator for modulating an audio signal transmitted from the compensator; and an output stage for outputting the modulated audio signal. Accordingly, audio quality can be improved directly for a listener by compensating the input signal damaged by periodical voltage drops.
