Abstract : The logic function of the combination section of a digital automaton is transformed into the normal form expressed as a tree-like structure and consisting of individual logic lines. The reliability of the combination section of the digital automaton is expressed as the reliability of the logic lines. To increase reliability, redundance or redundance with restoration is used with each logic line. The reliability of a single-logic line, the reliability of 3 logic lines in parallel, and the reliability of a logic line with triple redundance and restoration (by element) - taking into account, errors in the input signals - are determined. The effectiveness of each logic line considered is determined by comparing its reliability with that of an equivalent line without redundance. It is shown that in the case of redundance with restoration the reliability of the lines with redundance is higher than that of lines without redundance when the probability of errors in the logic elements does not exceed 0.0238, even when the number of logic elements tends toward infinity.
