Abstract

A noise source (113 or 217) is coupled to an analog-to-digital converter (115 or 219) so as to remove at least some unwanted spectral components from the analog-to-digital converter (115 or 219) output. In one embodiment, the noise source (113 or 217) is comprised of a sigma-delta digital-to-analog modulator.
