…The simplest error detection method is to add one redundant bit to each series of bits, and to set the number of 1s in that bit to either even or odd. By disturbing the even-oddness, a single-bit error can be detected. The code added in this way is called an error detection code. By increasing the number of redundant bits, a code can be formed that can not only detect errors but also correct them. Various code construction methods are known. Code [Saito Tadao]. … *Some of the terminology that mentions "error detection code" is listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…もっとも簡単な誤り検出方式は,一連のビットごとに1ビットの冗長ビットをつけ,その中に存在する〈1〉の数を偶数,または奇数のいずれかに定めておく方式で,偶奇性が乱されることで1ビットの誤りを検出できる。このように付加される符号を誤り検出符号といい,冗長ビットの数を増加すれば,誤りの検出のみならず訂正も可能な符号が形成でき,種々の符号構成法が知られている。符号【斉藤 忠夫】。… ※「誤り検出符号」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
