Приводятся правила построения троичных кодов с суммированием, которые по своим свойствам схожи с бинарным кодом Бергера. Рассматриваются две модификации троичного кода с суммированием — коды с суммированием в кольце вычетов по модулям μ=3 и μ=9 — и некоторые характеристики обнаружения ошибок этими кодами. Показано, что доля необнаруживаемых троичными кодами с суммированием ошибок кратностью d от общего числа ошибок данной кратностью является постоянной величиной, не зависящей от длины информационного вектора.</p></abstract><trans-abstract xml:lang="en"><p>Ternary summation codes with simple construction rules, suitable for the digital self-checking circuits synthesis operating in ternary logic and able of detecting any non-compositional errors in information vectors (when the number of characters of each type is preserved), are considered. Rules for constructing the ternary sum codes, similar in its properties to the Berger binary code, are given. Two modifications of the ternary sum code are described – sum codes in the residues modulo μ=3 and μ=9 ring. Several characteristics of error detection by the codes are described. It is shown that the proportion of errors of multiplicity d, undetectable by binary summation codes, of the total number of errors of the given multiplicity, is a constant value independent of the information vector length.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отказоустойчивые и самопроверяемые цифровые устройства и системы</kwd><kwd>помехоустойчивое и помехозащищенное кодирование</kwd><kwd>троичные коды с суммированием</kwd><kwd>троичные модульные коды с суммированием</kwd><kwd>обнаружение ошибок в информационных векторах</kwd><kwd>необнаруживаемая ошибка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fault-tolerant and self-testing digital devices and systems</kwd><kwd>noise-resistant and noise-proof coding</kwd><kwd>ternary codes with summation</kwd><kwd>error detection in information vectors</kwd><kwd>undetectable error</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гаврилов М.
