PWM/SD and clock jitter

I'm not sure if I need to worry a lot about this.  Anyways, this
document by Bob Adams (Analog Devices) [1] is an interesting read
about current technology.  Especially the part about class D amps is
quite relevant.

The whole workshop[2] seems quite interesting:

    While high oversampling is a preferred technology in digital
    signal encoding, the advantages of redundancy are far from clearly
    understood. Single bit quantization schemes such as Sigma-Delta
    Modulation are intimately connected with number theory, dynamical
    systems, and stochastic processes. These methods are also used in
    other applications such as halftoning. The workshop will bring
    together selected experts, from a variety of scientific
    disciplines, whose work interfaces coarse quantization
    techniques. The focus of the workshop will be to explain the
    benefits of redundancy in this setting and to describe the
    compelling open problems.
