ABSTRACT:
A method of synchronizing static or dynamic dissimilar output sampling rates of multiple outputs of an integrated switching amplifier uses the step of synchronizing dissimilar static or dynamic sampling rates of multiple outputs to yield improved sonic quality, higher efficiency, lower EMI or other benefits. According to the preferred embodiment, the synchronizing is carried out with respect to pulse leading edges.
