Abstract: A decoding method for biphase-encoded data is provided. The decoding method includes detecting falling-edge transitions in the biphase-encoded data to decode according to a time difference (Δt) between each two adjacent falling-edge transitions and the logic value of previous bit. When Δt is 1 bit period and previous bit is logic 1, it's determined that present bit is logic 1. When Δt is 1 bit period and previous bit is logic 0, it's determined that present bit is logic 0. When Δt is 1.5 bit periods and previous bit is logic 1, it's determined that present and next bits are both logic 0. When Δt is 1.5 bit periods and previous bit is logic 0, it's determined that present bit is logic 1. When Δt is 2 bit periods and previous bit is logic 1, it's determined that present and next bits are logic 0 and 1 respectively.

Abstract translation: 提供了一种用于双相编码数据的解码方法。 解码方法包括检测双相编码数据中的下降沿转换，以根据每两个相邻下降沿转换之间的时间差（＆Dgr; t）和先前位的逻辑值进行解码。 当＆Dgr; t为1位周期，前一位为逻辑1时，确定当前位为逻辑1.当＆Dgr; t为1位周期，前一位为逻辑0时，确定当前位为逻辑0。当＆Dgr ; t为1.5位周期，前一位为逻辑1，确定当前位和下位均为逻辑0.当＆Dgr; t为1.5位周期，前一位为逻辑0时，确定当前位为逻辑1。 ＆Dgr; t为2位周期，前一位为逻辑1，则确定当前和下一位分别为逻辑0和1。
