Abstract
An analog signal is quantized over a range of quantizing levels, each level being associated with a digital signal, and wherein the digital signals which are associated with a predetermined band of the quantizing levels have zero disparity. In accordance with one aspect, those digital signals which are outside the aforementioned band and which have non-zero disparity are selected to represent corresponding quantizing levels in such a manner that positive and negative disparity signals are selected, alternately, to represent quantized analog signals which are disposed outside the predetermined band. In accordance with another aspect, those zero disparity digital signals having the smallest run-lengths are assigned to represent quantizing levels which are disposed substantially in the center of the quantizing range, and those zero disparity digital signals having progressively larger run-lengths are assigned to represent quantizing levels which are disposed progressively farther from the center of the range.
