Abstract
A loudspeaker control circuit includes a bit splitter, a complement module and a digital-to-analog converter. The bit splitter divides a data item representing an acoustic signal into a high order bit group and a low order bit group. The complement module determines a complement of at least one of the high order bit group and the low order bit group. The complement module may be connected in series to the digital-to-analog converter. The digital-to-analog converter converts the high order bit group and the low order bit group from a digital format to an analog format.
