发明名称 Digital requantization process and devices
摘要 The invention relates to the digital signal requantization, at a given quantization step size, of a first word received in a first period of time and encoded in a first number of bits, into a second word, with a quantization error equal to a third number. A sequence of third words is outputted, equal to the second word, with the sequence subdivided into a first group comprising a number of third words that is equal to the third number and a second group of third words. Before outputting them, the correction means adds a least significant bit to the third words of the first group and adds or subtracts least significant bits to or from the third words of the second group, such that the sum of the least significant bits added to and subtracted from the second group is zero.
