This paper clarifies some of the confusion, which has arisen over the efficacy of dither in PCM and Sigma-Delta Modulation (SDM) systems. It presents a means of analysing "in-band" idle tone structure and describes a fair means of comparison between PCM and SDM. It presents results, which show that dither can be effective in S-D systems.
