By using a programmable circuit arrangement it is possible to effect the logical connection of binary input signals. The arrangement comprises a matrix (MA) of transmission lines (DL) and coupling lines (KL) at whose coupling points are arranged coupling elements (KE) according to a function table to be produced. The coupling elements (KE) can assume three different states, the first corresponding to a binary 1, the second to a binary 0 and the third to a binary 1 or a binary 0. Each data transmission line (DL) can be operated as an input or an output by means of a control signal (ST) applied to an input circuit and to an output circuit (AG). The input signals coupled to a coupling line (KL) by data transmission lines operated in the input mode are subjected, on the coupling line, to an AND-connection. On the other hand, the signals coupled by the coupling lines (DL) to a data transmission line (DL) operated in the output mode are subjected, on the data coupling line, to an OR-connection. Depending on the state of the coupling elements (KE), set in accordance with a function table, it is possible to achieve different connections by using the data transmission lines (DL) as inputs and as outputs. |
