High speed digital signal transmitting pulse waveform and its generating method and device

The present invention is high speed digital signal transmitting pulse waveform. The waveform is the homogeneous combination of two kinds of semi-waves with pulse width of exponential times of 2 of the basic clock pulse width. When the basic clock pulse period is the integral times of the transmitted pulse number, the waveform is ideal homogeneous square wave with equal pulse width and homogeneous distribution. When the basic clock pulse period is not the integral times of the transmitted pulse number, the waveform is one homogeneous combination of the basic square wave and one other square semi-wave with pulse width of two-times that of the basic square wave and is distributed homogeneously in the whole transmission period. The waveform corresponds to a logic state with period start and end of logic 0 or 1. Compared with ideal homogeneous square wave, the waveform transmits pulse number with difference at most half one pulse. 一种高速数字信号传输脉冲的波形，该波形是由传输周期基本时间脉冲的2的指数倍波宽的两种半波所均匀组合而成，在基本工作时间脉冲周期为传输脉冲数目的整数倍时，该波形的各方波波宽相等且均匀分布于整个传输周期的理想均匀方波，在基本工作时间脉冲周期为传输脉冲数目的非整数倍时，该波形由一种基本方波及另外一种波宽为基本方波两倍的方波的半波所均匀混合组成，且均匀分布于整个传输周期；该波形是以周期的一半作分隔为对称，具有2倍数重现性；该波形所对应的逻辑状态，在一个周期的开始及结束，其逻辑必固定为0或1；该波形所传送的脉冲数，与波宽相等且均匀分布的理想均匀方波波形所传送的脉冲数比较，最多仅差半个脉冲。
