Abstract
(EN)
A signal generator consistent with certain embodiments of the invention has a reference clock (34) producing a periodic sequence of reference clock output pulses. A window generator (38) generates a plurality of time windows through which a selected plurality of the reference clock output pulses are selectively passed as windowed pulses so that the windowed pulses form a selected pattern of pulses. A programmable delay (46) has resolution of delay that has finer time granularity in delay than the period of the clock output pulses. The programmable delay (46) delays each of the windowed pulses by a programmed delay time to thereby provide a timing correction to the windowed pulses to produce an output pattern of pulses.
(FR)
L'invention concerne un générateur de signaux qui, dans certains modes de réalisation, est muni d'une horloge (34) de référence produisant une suite périodique d'impulsions de sortie d'horloge de référence. Un générateur (38) de fenêtres génère une pluralité de fenêtres temporelles à travers on fait passer sélectivement une pluralité choisie des impulsions de sortie d'horloge de référence sous forme d'impulsions fenêtrées de telle sorte que les impulsions fenêtrées forment un motif choisi d'impulsions. Un retard programmable (46) présente une résolution de retard donnant une granularité temporelle du retard plus fine que la période des impulsions de sortie d'horloge. Le retard programmable (46) retarde chacune des impulsions fenêtrées d'un temps de retard programmé pour appliquer ainsi une correction chronologique aux impulsions fenêtrées afin de produire un motif d'impulsions de sortie.
