Abstract
Description
Gegenstand der Erfindung ist eine elektronische Umcodierschaltung für die Umcodierung von 5211-codierten Dezimalziffern in 1-aus-10-codierte Dezimalziffern.The invention relates to an electronic recoding circuit for the recoding of 5211-coded decimal digits in 1-out-of-10 coded decimal digits.
Im Gegensatz zur Umcodierschaltung nach der Haupt-Patentanmeldung hat diese Umcodierschaltung keine Oder-Schaltung mit 7 Eingängen und andererseits 2 zusätzliche Oder-Schaltungen 19 und 20 mit je 3 Eingängen.In contrast to the transcoding circuit according to the main patent application, this transcoding circuit has no OR circuit with 7 inputs and, on the other hand, 2 additional OR circuits 19 and 20 with 3 inputs each.
In Fig. 1 ist die Umcodierschaltung 1 dargestellt, welche 5211-codierte Dezimalziffern in 1-aus-10-codierte Dezimalziffern umwandelt. In Fig. 2 ist der Dezimal-1-aus-10-Code dargestellt und in Fig. 3 der 5211-Code. In Fig. 4 ist die Gegen-Umcodierschaltung 2 dargestellt, welche 1-aus-10-codierte Dezimalziffern in 5211-codierte Dezimalziffern umwandelt.In Fig. 1, the Umcodierschaltung 1 is shown that 5211-coded decimal digits converts 10-encoded 1-of-decimal digits in. In FIG. 2, the decimal 1-of-10 code is illustrated in Fig. 3 of the 5211 code. FIG. 4 shows the counter-recoding circuit 2 , which converts 1-out-of-10 coded decimal digits into 5211-coded decimal digits.
Die 5211/1-aus-10-Umcodierschaltung 1, welche in Fig. 1 dargestellt ist, besteht aus 16 Und-Schaltungen 2 bis 17 mit je 2 Eingängen und der Oder-Schaltung 18 mit 4 Eingängen und den Oder-Schaltunggen 19 und 20 mit je 3 Eingängen und der Oder-Schaltung 21 mit 4 Eingängen und 5 Negier-Schaltungen 22 bis 26 und den zugehörigen Leitungen. Die Eingänge M sind mit den Buchstaben A bis D gekennzeichnet. Der Eingang A hat die Wertigkeit 1; der Eingang B hat auch die Wertigkeit 1; Der Eingang C hat die Wertigkeit 2; der Eingang D hat die Wertigkeit 5. Die Ausgänge N sind mit den zugehörigen Zahlenwerten (Ziffern 0 bis 9) gekennzeichnet.The 5211/1 out of 10 recoding circuit 1 , which is shown in FIG. 1, consists of 16 AND circuits 2 to 17 with 2 inputs each and the OR circuit 18 with 4 inputs and the OR circuit genes 19 and 20 with 3 inputs each and the OR circuit 21 with 4 inputs and 5 negation circuits 22 to 26 and the associated lines. The inputs M are marked with the letters A to D. The input A has the value 1; input B is also valued at 1; The input C has the value 2; input D has a value of 5. Outputs N are marked with the associated numerical values (digits 0 to 9).
