parity sum 奇偶校验和 In a parity system, the number of 1bits in a bit pattern which determines whether the pattern has been corrupted. The bits are added by modulo2, a total of “1” indicates an error in an even parity system and a total of “0” indicates an error in an odd parity system. 在奇偶校验方法中,位于某个位模式中二进位1的数目, 它决定该位模式是否被破坏了。这些二进位以模数2相加,其总和为1表示在偶校验法中出错。 在奇校验法中,其总和为0表示出错。 |
