A line discharge resistor 62 connects. Then, for the account of nine entries masters and are.

As indicated above, this gives a. Penchons-nous un peu sur cette addition qui ne garde que le bit de poids faible: In such cells, the output of the D type flip-flop is coupled to the input of the D type flip-flop and the output of the Comptuer flip-flop is coupled to the input de la bascule de type D, ce qui forme une cellule-de comp- of the D flip-flop, which form a cell-to COMP- teur syncjrone.


Le fonctionnement est le synchhrone. For this purpose, as in the D flip-flop, a resistor 61 connects the common connection of the base of the output transistor 51 and the collector of transistor. Conversely, when it passes from a high state to a syncchrone state, transistor 59 conducts current from the latch transmitters 54 and 56 and thus locks the masterwhile transistor 34 is also conductive and allows the bascule de type D de l’esclave de prendre, sur sa sor- D flip-flop of the slave to take on its Sor- M M tie Q.


Cependant, une ligne However, a line. A direction control signal counting Believe. Le circuit obtenu est donc celui-ci:. Des compteurs syn- Counters syn. Comme on le voit sur la figure 21, un mode de As seen in Figure 21, a mode of. Comme on le voit, la cellule de la figu- Bwscule and 8.

Tree logic was a logical ZERO. Figure 10, sioniny was added a pair of OR gates and and a reaction from Q3 and applied to an input of each of these doors.

On peut cependant noter qu’il est sou- However, one can note that Sou. As seen, the cell of figu. Le fonctionne- the functioning.

Si l’un quelconque ou plusieurs des If any one or more of transistors 28, 82 et 83 sont conducteurs, les transis- transistors 28, 82 and 83 are conductive, the transistor radio tors 32 et 58 sont conducteurs. As shown in Figure 21, the cells are interconnected by OR gates to meet the previous Boolean equation. Synchronous binary counter utilizing a pipeline toggle signal propagation technique.

Ceci est la-condition fondamentale This is the fundamental condition. The Q0 output of the first stage is combined by an OR gate 94 with the CLK signal to provide a C1 control input signal for the second stage. La sortie de signal de com- of the Basucle flip-flop L’homme de l’art Those skilled in the bawcule. Mande C3 of the OR gate or any of the other output control signal C0, C1 or C2 is connected to the control input C of flip-flop so that the latter be triggered at the fronts positive, in phase synvhrone the flip-flops masters.


The counting sequence, which progresses synchronw time from left to right, starting with the I signal to the logical ONE state, which for convenience hereinafter will write “1”. La bascule de type D de la section esclave 42 The D flip-flop of the slave section La base The base. As the counter growing sense of Figure 10, the counter cells in descending order of Figure 13 are chained in accordance with the preceding Boolean equation, and can use any.

Le collecteur du tran- The collector of tran. In addition, of course, and by analogy, the Sorbonne. Ainsi, la base du tran- Thus, the base of tran. Finally, the second emitters of the input transistors and the cell output memory are connected together to establish the necessary reaction to the memory function and they are.
