Theoretical sufficient conditions are presented that ensure that the quantization noise from every constituent digital delta-sigma (16) modulator in a multistage digital 16 modulator is asymptotically white and uncorrelated with the input. The conditions also determine if spectral shape can be imparted to the dither's contribution to the power spectral density of the multistage digital 16 modulator's output. A large class of popular multistage digital 16 modulators that satisfy the conditions are identified and tabulated for easy reference.
