Abstract
A sequence of digital data values is processed by deriving the average W.sub.n of two of the data values X.sub.n-1 and X.sub.n+1. If W.sub.n lies within the quantization step q centered on the data value X.sub.n, W.sub.n is adopted as a modified value of X.sub.n, but if W.sub.n lies outside the quantization step the modified value of X.sub.n is taken to be X.sub.n +q/2 or X.sub.n -q/2, depending on whether W.sub.n is greater or less than X.sub.n.
