ABSTRACT:
The present invention relates to a converter converting an input digital signal into an output digital signal. Said converter comprises in particular a set of shift registers able to contain samples of the input or output digital signal. It also comprises a calculation unit able to supply a shift signal (4) to said set of registers. Said calculation unit comprises a first storage unit (51) able to contain a value of a conversion ratio or of its inverse, so that the value stored is between 0 and 1. It also comprises a second storage unit (52) able to contain, at a cycle time i+1, i being an integer, a future signal (8) equal to a sum of a current signal (7) contained in the second unit at a cycle time i and of the content of the first storage unit. The shift signal then results from an exclusive OR function (54) between a most significant bit of the current signal (71) and a most significant bit of the future signal (81).
