Abstract
Description
Gegenstand der Erfindung ist eine Umcodierschaltung für die Umcodierung von 5211-codierten Dezimalziffern in 1-aus-10-codierte Dezimalziffern. Erfindungsgemäß hat diese Umcodierschaltung keine Und-Schaltungen mit je 4 Eingängen, sondern nur 16 Und-Schaltungen mit je 2 Eingängen und 3 Oder-Schaltungen und 4 Negier-Schaltungen.The invention relates to a recoding circuit for the Recoding 5211-encoded decimal digits into 1-out of 10-encoded Decimal digits. According to the invention, this recoding circuit no AND circuits with 4 inputs each, but only 16 AND circuits with 2 inputs and 3 OR circuits each and 4 negating circuits.
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 Dezimal-Ziffern 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 der Oder-Schaltung 19 mit 7 Eingängen und der Oder-Schaltung 20 mit 4 Eingängen und den Negier-Schaltungen 21 bis 24 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 19 with 7 Inputs and the OR circuit 20 with 4 inputs and the negating circuits 21 to 24 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; 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 ).
Die 1-aus-10 - 5211-Umcodierschaltung 2 besteht aus 4 Oder- Schaltungen 41 bis 44 und den zugehörigen Leitungen. Die Eingänge M sind mit den zugehörigen Zahlenwerten (Ziffern 0 bis 9) gekennzeichnet. Die Ausgänge N sind mit den Buchstaben A bis D gekennzeichnet. Der Ausgang A hat die Wertigkeit 1; der Ausgang B hat auch die Wertigkeit 1; der Ausgang C hat die Wertigkeit 2; der Ausgang D hat die Wertigkeit 5.The 1-out-10 - 5211 recoding circuit 2 consists of 4 OR circuits 41 to 44 and the associated lines. The inputs M are marked with the associated numerical values (digits 0 to 9 ). The outputs N are marked with the letters A to D. The output A has the value 1; output B also has a value of 1; the output C has the value 2 ; the output D has the value 5.
Die in Fig. 1 dargestellte Umcodierschaltung wandelt Dezimalziffern von dem in Fig. 3 dargestellten 5211Code in den in Fig. 2 dargestellten 1-aus-10-Code um.The transcoding circuit shown in FIG. 1 converts decimal digits from the 5211 code shown in FIG. 3 to the 1-out-of-10 code shown in FIG .
Die in Fig. 4 dargestellte Umcodierschaltung wandelt Dezimalziffern von dem in Fig. 2 dargestellen 1-aus-10-Code in den in Fig. 3 dargestellten 5211-Code um.The conversion circuit shown in FIG. 4 converts decimal digits from the 1-out-of-10 code shown in FIG. 2 to the 5211 code shown in FIG. 3.
