Abstract
A method and device for producing an accurate approximation of a digital input word translated by a monotonic transfer function. The digital word is translated into a non-monotonic output word comprised of a closest-approximation component and an error component. The error component is zero for regions in which each consecutive input word produces a unique closest-approximation component. In regions in which each consecutive input word produces the same closest-approximation component the error signal represents the number of consecutive input words which produce the same closest-approximation component, and the position within that run of consecutive input words occupied by the present input word.
