Reduction of spectral distortion in class D amplifiers by an enhanced pulse width modulation sampling process
TL;DR: In this article, an enhanced sampling process was proposed to reduce spectral distortion in the output of digital pulse width modulated class D amplifiers, which can be adjusted such that the spectra produced by the process can take a number of forms for the same signal.
Improved sampling process for a digital, pulse-width modulated, class D power amplifier
TL;DR: A pulse-width modulation sampling process has been derived which is suitable for implementation in an entirely digital system, but has a performance comparable with that of natural sampling, and should be possible to realise a high efficiency, high performance class D power amplifier.
Journal ArticleDOI
Digital sampling process for audio class D, pulse width modulated power amplifiers
TL;DR: An alternative sampling process is described which is suitable for digital implementation yet introduces the low levels of distortion usually associated with natural sampling.
Journal ArticleDOI
Distortion analysis and reduction in a completely digital PWM class D power amplifier
Journal ArticleDOI
Distortion minimisation in pulse width modulated systems using a digital sampling process
TL;DR: In this paper, a technique that allows the PWM sampling process to be varied over a range of possibilities which offer different compromises between the type of distortion produced by natural and uniform sampling is described.
