A device for generating synchronous numeric signals, including a first signal generator which supplies a numeric reference signal having a first frequency and a first period; and a second signal generator which generates an internal numeric signal having a second frequency and a second period, and a synchronized numeric signal. In addition, the second signal generator includes a predictor which generates, with a third period and a third frequency higher than the first frequency and the second frequency, estimated samples correlated to a current sample and to a predetermined number of former samples of the internal numeric signal. The predictor, in turn, includes a selection circuit controlled by the first signal generator for selecting one among the estimated samples in each reference period, the synchronized numeric signal being formed by the selected estimated samples.
