The drawing shows the proposed device.

The device contains two decoders 1 and 2, ten elements OR 3-12, an adder 13 modulo three, an adder 14 modulo two, a comparison unit 15, the first and second groups of information inputs 16 and 17, and 18 control bits Dov, exit 19 errors.

The device works as follows.,

The inputs of the decoders 1 and 2 receives the information word from the first and second groups of information inputs 16 and 17 of the device. The outputs of the decoders are connected to the elements of ШШ 3,4,6,7,8,9,11 and 12 in such a way that. elements OR 4, 6, 9 and 1 group the outputs, corresponding to odd information at the inputs of the decoders, and elements OR 3.7, 8 12 - even.

The outputs of the decoders corresponding to the information on their inputs, having a modulo three residue equal to one, are connected to the inputs of the OR elements 3,4, 8 and 9. The outputs of the decoders corresponding to the information. at their inputs, having a modulo three residue equal to two, are connected by the inputs of the elements OR 6, 7, 11 and 12. Thus, at the outputs of the elements OR 3 and 7 and the elements IL 8 and 12, modulo three information coming from information input 16 and information input 17, which are summed in the adder 13 modulo three, the output of which forms the remainder of the total y. formation word, incoming n inputs of the device.

At the output of the modulator 14 modulo two, a remainder is formed modulo two information words arriving at the inputs of the device. The calculated residues modulo two and three are sorted in block 15 comparison with the console bits received at block 15 comparison with inputs 18. In case of noncomparison at the output of block 15
