Abstract
The invention concerns a digital coder subject to a compression law having multiple linear segments with slopes decreasing in geometrical progression having a ratio of 1/2, in which a chain of threshold detectors in a linear progression is used a first time to determine the number of the segment, then a second time to determine the position of the level on the segment.
