    • Circuits and methods for transmission of digital data between two or more devices via powerline particularly suited for use in high attenuation, high noise commercial/industrial powerline environments, including transmission of pulses generated by a capacitor charged in the positive half cycle of the sine wave and discharged during the negative half-cycle, placing the pulse at one of two predetermined signal timing positions related to zero voltage crossing points or to previously transmitted pulses so that the pulses are substantially in the powerline temporal quiet zone near zero crossing and so that the powerline voltage at the time of the pulse is additive to the capacitor voltage.
    • 通过特别适用于高衰减,高噪声商业/工业电力线环境的电力线,在两个或多个设备之间传输数字数据的电路和方法,包括由在正弦波的正半周期充电的电容器产生的脉冲的传输,以及 在负半周期期间放电,将脉冲放置在与零电压交叉点相关的两个预定信号定时位置中的一个或先前发送的脉冲,使得脉冲基本上处于零交叉附近的电力线时间安静区域,并且使得电力线 脉冲时的电压与电容器电压相加。
