Abstract
A device for automatically converting a digital sample sequence X(n) inputted at a first frequency f and converted into an output digital sample sequence Y(m) at a second frequency f which is smaller than f . An interpolator-decimator assembly having a decimation rate equal to &ggr;, selected so as to correspond to the frequency offset f /f is based on a polyphased filter having p tables of q elements each, said filter being designed such that samples X(n) are input at the f frequency and table components are activated according to clocking of a second clock derived from the f clock and wherein one clock pulse is removed.
