| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an amplifier and method capable of suppressing power consumption.SOLUTION: The amplifier, which modulates a carrier frequency with a digital signal and amplifies the modulated signal, includes: a determination section that determines at least one of sound quality required for a digital signal, a sound source of the digital signal and a sound type of the digital signal; a carrier frequency setting section that sets a carrier frequency according to the determination result; and a pulse duration modulation section that pulse-duration modulates a carrier frequency according to a digital signal. |
