Abstract

In this electronic modulo-10 up/down counter (Figure 6), the resetting of the flip flops is also preselected by the internal counting output as in the electronic counter according to the main patent application P 3047169.3. In this electronic counter, the flip flops are combined with negating delay circuits, with the exception of the switching flip flop (6) which is combined with a special monostable flip flop. The flip flop input circuits also consist of two OR gates having two inputs each and four AND gates having two inputs each in this up/down counter. <IMAGE>

Description

Electronic counter in 1-out-of-10 code

The subject of the invention is the further improvement of the modulo 10 counter according to the Raupt patent application P 31 28 764.6 and the additional patent applications P 31 30 198.3 and P 31 39 615.1). This improvement is that the counting flip-flopps and the reversing flip-flop with special delay circuits according to P 31 44 376.1 have been combined to achieve a sufficiently good delay. These delay circuits are therefore necessary to avoid several counting flip-flopps from one counting pulse successively tilt into their counting position and thereby an incorrect counter reading and thus cause a false display. The counting flip-flopps of these electronic ones Counters are equipped with a delayed negating circuit according to FIG. 10 from P 31 44 376.1 combined, which are controlled by the reset output of the counting flip-flopps. The reversal flip-flopps of these electronic payers have a delay circuit according to Figure 2 or 6 of P 31 44 376.1 combined, which from the left-hand exit the reversal flip-flopps are controlled.

If the decades of the electronic up counters type 1 and 2 are formed in accordance with the detail shown in Figure 9, takes place Flip-flopp control via normal diode-and-circuits. In the opposite case (From education according to FIG. 12) this control takes place via AND circuits with a active input (capacitor).
