摘要
We propose a new structure of a self-checking combinational device where, based on the properties of parity and Berger codes, as well as a code with the detection of all double errors in information vectors, the problem of detecting all single faults of logical elements can be solved without transforming the structure of the source device. The properties of binary codes with the detection of all double errors that can be used in constructing the proposed structure are considered. We give an example of constructing a new structure.
