Abstract

Ein Verfahren zur Summenbildung von N > 1 bandbegrenzten Zeitsignalen mit je einer Bandbreite ≤ B, die als analoge und/oder digitale Abtastwerte vorliegen, wobei die jeweilige Abtastfrequenz fA > 2B ist, ist dadurch gekennzeichnet, daß die Abtastwerte aller N Zeitsignale zeitlich zueinander versetzt überlagert und gemeinsam in ein Tiefpaßfilter (12) der Filterbandbreite B' > B eingegeben werden, und daß am Ausgang des Tiefpaßfilters (12) ein Summensignal abgegriffen wird. Damit kann die Summation mit einer erheblich geringeren Rechenzeit durchgeführt werden, gegebenenfalls eine Vielzahl von langsamen und teueren Addiergliedern eingespart werden und eine Dämpfung der Signale bei der Verarbeitung und der damit einhergehende Informationsverlust minimiert werden.
