Abstract:
1. A requantization device comprising: an input for receiving, in a first period of time, a first word encoded in a first whole number of bits; a first truncation unit for requantization, at a given quantization step size, of the first word into a second word in a second whole number of bits that is strictly less than the first whole number; a second truncation unit for determining a third number equal to the value of a fourth number of least significant bits of the first word, with the fourth number being equal to the difference between the first whole number and the second whole number; an output for outputting, during a fourth number of periods following the first period of time, a sequence of third words each equal to the second word for the current period of time, with the sequence comprising a first group comprising a number of third words that is equal to the third number and a second group of third words distinct from the first group; and a correction unit configured to:
