Abstract
A system, a device and a method for pulse width modulation is disclosed. One embodiment includes a pulse width modulation device, a first pulse width modulation mapper for pulse width modulation of a data signal, or a signal derived therefrom, and a second pulse width modulation mapper for pulse width modulation of a reference signal, or a signal derived therefrom. In one or more embodiments, the data signal e.g., can be a signal for a mono audio channel, or a signal for a stereo audio channel. The reference signal can be a signal including a constant signal level or a signal including a non-constant signal level an offset signal.
