ABSTRACT:
A digital dither generator is described which produces a series of discrete analog values which remain constant for each repetition of a signal being digitized. These analog values are summed with the analog input value being digitized. The dither states exhibit two useful characteristics; a bit-reversal scheme in which a sequence of dither values is used to progressively maximize the resolution of the digitizer and a technique of offsetting the values by a known amount to statistically improve digitizer accuracy.
