Abstract

Using the circuit according to the subject of the invention, which is called an "exchange circuit", the relevant 1-out-of-10 coded decimal number can be passed straight on or increased by the number 5, if it is in the lower range 0 to 4, and can be passed straight on or decreased by the number 5, if it is in the upper range 5 to 9. <IMAGE>

Description

Gegenstand der Erfindung ist eine Wechsel-Schaltung im Dezi­ mal-1-aus-10-Code, mittels der in bestimmten Fällen die be­ treffende Dezimalziffer um die Zahl 5 angehoben wird, wenn sie im unteren Bereich (0 bis 4) liegt und um die Zahl 5 ge­ senkt wird, wenn sie im oberen Bereich (5 bis 9) liegt.The invention relates to an alternating circuit in deci times-1-out of 10 code, by means of which the be appropriate decimal digit is increased by the number 5 if it is in the lower range (0 to 4) and by the number 5 ge is lowered if it is in the upper range (5 to 9).

Diese Wechsel-Schaltung ist auf der Zeichnung dargestellt.This changeover circuit is shown on the drawing.

Diese Wechsel-Schaltung besteht aus 10 Oder-Schaltungen 1 mit je 2 Eingängen und 10 Und-Schaltungen mit je 2 Ein­ gängen und der Negier-Schaltung 3 und den zugehörigen Leit­ ungen. Die Eingänge A und die Ausgänge B sind mit den zuge­ hörigen Zahlenwerten (Ziffern 0 bis 9) gekennzeichnet.This change-over circuit consists of 10 OR circuits 1 with 2 inputs each and 10 AND circuits with 2 inputs each and the negation circuit 3 and the associated lines The inputs A and outputs B are with the associated numerical values (Numbers 0 to 9).

Die Wirkungsweise ergibt sich wie folgt: Wenn an den Ein­ gängen A dezimal-1-aus-10-codiert die Ziffer 2 anliegt und am Steuer-Eingang E L-Potential anliegt, hat die Negier­ schaltung 3 an ihrem Ausgang H-Potential und haben die Er­ gebnis-Ausgänge B dezimal-1-aus-10-codiert die Ziffer 2. Wenn an den Eingängen A dezimal-1-aus-10-codiert die Ziffer 2 anliegt und am Steuer-Eingang E H-Potential anliegt, hat die Negier-Schaltung 3 an ihrem Ausgang L-Potential und ha­ ben die Ergebnis-Ausgänge B dezimal-1-aus-10-codiert die Ziffer 7.The operation is as follows: If transitions to the A A decimal-1-of-10 encoding bears the numeral 2, and at the control input E L potential is applied, the Negier has circuit 3 at its output H-potential and have the result outputs B decimal-1-out-10-coded the number 2. If at the inputs A decimal-1-out-10-coded the number 2 is present and at the control input E has H potential, the Negier circuit 3 at its L-potential output and have the result outputs B decimal-1-out of 10-coded the number 7 .

Bei der Wechsel-Schaltung Type B ist die Negier-Schaltung 3 an der Stelle c angeordnet.In the case of the changeover circuit type B , the negation circuit 3 is arranged at point c .
