PRESET CODE COMBINATION PULSE SELECTOR Russian patent published in 1997 - IPC

FIELD: pulse engineering, can be used in data processing, control and measuring devices, in particular, can be used in devices intended for reception of binary pulse position codes for selection of a sequence of preset code combinations from the input stream of data, for instance, for selection of address parts of data words and for subsequent switching of the remaining parts of these data words. SUBSTANCE: preset code combination pulse selector has the first and second shift registers, first, second and third decoders, pulse counter, first and second flip-flops, first and second OR gates, clock pulse generator, first and second AND gates, inverter, reset line, clock line, data input and output lines, it also uses a switch, storage third AND gate, PS flip-flop, fourth decoder and a group of n AND gates, whose outputs are connected to the additional selector outputs (from the first to the n-th), and the (n+1)-th additional output of the selector is connected to the output of the third AND gate and to the S-input of the RS flip-flop. The output line is connected to the output of the second AND gate and to the second input of the first OR gate, whose output os connected to the R-input of the RS flip-flop and to the storage control input, and the first input - to the selector reset line. EFFECT: expanded functional abilities. 4 dwg
