Abstract

Verfahren zur Summen-richtigen Aufteilung eines Tonfrequenzsignals auf N Ausgangskanäle. Es werden hierzu genau N-1-Filter verwendet und zumindest 1 Diffe­ renz-Summierer, der zu einer Gruppe von Filtern mit ge­ meinsamem Eingangssignal das zugehörige Komplemen­ tärsignal bildet. Verwendet man nur einen Differenz-Sum­ mierer, so entsteht eine einstufige Schaltungsanordnung, bei der das Tonfrequenzsignal innerhalb einer Stufe auf N Ausgänge verteilt wird. Verwendet man dagegen mehr als einen Differenz-Summierer, so erhält man eine mehr­ stufige Schaltungsanordnung, bei der das Tonfrequenz­ signal in mehreren Stufen auf N Ausgänge verteilt wird. Procedure for correctly dividing up a sum Audio frequency signal on N output channels. It will for this purpose exactly N-1 filters are used and at least 1 difference renz totalizer, which belongs to a group of filters with ge common input signal the associated complemen Tärsignal forms. If you only use a difference sum mier, a single-stage circuit arrangement is created, at which the audio frequency signal is within one step N outputs is distributed. On the other hand, you use more than a difference totalizer, you get one more stage circuit arrangement in which the audio frequency signal is distributed in several stages to N outputs.
