摘要
In order to code a digital signal (IM), the invention combines a breakdown of the digital signal into frequency subbands and a finite state vectorial quantization of the subbands. The digital signal is analysed in a plurality of frequency subbands distributed in accordance with at least two different resolutions, and then the subbands of higher resolution are coded by finite state vectorial quantization as a function of the subbands of lower resolution.
