发明名称 Digital sample sequence conversion device
摘要 A device for automatically converting a digital sample sequence X(n) inputted at a first frequency fe and converted into an output digital sample sequence Y(m) at a second frequency fs which is smaller than fe. An interpolator-decimator assembly having a decimation rate equal to gamma, selected so as to correspond to the frequency offset fe/fs 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 fe frequency and table components are activated according to clocking of a second clock derived from the fe clock and wherein one clock pulse is removed.
