This paper clarifies some of the confusion which has arisen over the efficacy of dither in PCM and Sigma-Delta Modulation systems. It describes a fair means of comparison between them. It presents results which show that dither is effective in Sigma-Delta Modulation systems and proposes methods for achieving optimum performance in both systems.
