摘要

The method of binary encoding of u00ecndices of quantification of an envelope signal, method for decoding an envelope signal, and corresponding encoding and decoding modules. The present invention relates to a module (402) for binary coding of a signal envelope, which comprises an encoding module (502) to encode a first mode of variable length.According to the invention,The encoding module to encode the first mode incorporates a detector saturation envelope and said encoding module (402) additionally includes a second encoding module (503) to encode a second mode in parallel with the encoding module (502) for cod Ificar first mode, and a mode dial (504) adapted to select one of two modes of coding as well as U.A function of a criterion of the length of the code and the result of the envelope saturation detector. Application for coding and processing of signals of audiofrequ00fcu00eancia.
