This paper presents a new approach to dither in Sigma-Delta Modulation (SDM) systems. In particular, it clarifies the position of the overload point in one-bit SDM systems and presents several overload control methods with comparisons of their efficacy. It then goes on to examine the problem of applying dither to one-bit systems and describes a new approach to applying high levels of dither. It presents results, which show that such dither can be effective in SDM systems.
