FIELD: physics, communication. ^ SUBSTANCE: invention is related to the field of communication and may be used in devices for transmission of discrete information in communication line with interferences. Device contains memorising register, unit of error detection, unit of error correction, switching unit, which consists of two "AND" circuits, two registers of generator polynomial, two summators by module two, two decoders, programmable logical matrix, comparison unit, processor, inverter. Also method is disclosed for correction of two errors in cyclic code, which is realised by this device. ^ EFFECT: increase of communication channels equipment interference protection. ^ 2 cl, 2 dwg, 1 tbl |
