Zusammenfassung:	A computer-implemented method is provided for coding a digital signal quantized on a given number Nd of bits and intended to be processed by a digital computing system, the signal being coded on a predetermined number Np of bits which is strictly less than Nd, the method including the steps of: receiving a digital signal composed of a plurality of samples, decomposing each sample into a sum of k maximum values which are equal to 2NP−1 and a residual value, with k being a positive or zero integer, successively transmitting the values obtained after decomposition to an integration unit for carrying out a MAC operation between the sample and a weighting coefficient.
