    • A data receiving apparatus capable of reducing bit errors caused by noise includes a threshold value calculation unit, a judgment timing output unit, a data judgment unit, and a majority-rule judgment unit. The threshold value calculation unit calculates a plurality of different threshold values to judge whether the status of a received signal is ‘1’ or ‘0’. The judgment timing output unit outputs a plurality of judgment timings in a one-bit section of the received signal. The data judgment unit compares the received signal with each of the threshold values at the judgment timings and judges whether the status of the received signal is ‘1’ or ‘0’. The majority-rule judgment unit decides, by majority rule, on the ‘1’ and ‘0’ statuses obtained by the data judgment unit in the one-bit section and outputs the majority of the ‘1’ and ‘0’ statuses as the signal status of the received signal.
    • 能够降低由噪声引起的位错误的数据接收装置包括阈值计算单元,判断定时输出单元,数据判断单元和多数判定单元。 阈值计算单元计算多个不同的阈值,以判断接收信号的状态是“1”还是“0”。 判断定时输出单元在接收信号的一位部分中输出多个判断定时。 数据判断单元在判断定时将接收信号与每个阈值进行比较,并判断接收信号的状态是“1”还是“0”。 大多数规则判断单元通过多数规则来决定由数据判断单元在一位部分中获得的'1'和'0'状态,并将大多数'1'和'0'状态输出为 接收信号的信号状态。
