Digital audio class D amplifiers require a digital process to convert the sampled audio signal into a pulse width modulated (PWM) signal. The present methods of generating PWM are either analogue (natural sampling) and are unsuitable for digital systems or use a digital process (uniform sampling) which introduces excessive distortion. An alternative sampling process is described which is suitable for digital implementation yet introduces the low levels of distortion usually associated with natural sampling.
