    • Systems for translating voltage levels of digital signals are provided. An exemplary system comprises a circuit board operative to use a first digital signal and a second digital signal. The first digital signal operates between a first voltage and a second voltage, with the first voltage corresponding to a logic 0 and the second voltage corresponding to a logic 1. The second digital signal operates between a third voltage and a fourth voltage, with the third voltage and the fourth voltage exhibiting an average value, the absolute value of which is at least an order of magnitude different than an average value of the first voltage and the second voltage. The circuit board is further operative to use the first digital signal to produce the second digital signal. Methods and other systems also are provided.
    • 提供了用于翻译数字信号电压电平的系统。 示例性系统包括可操作以使用第一数字信号和第二数字信号的电路板。 第一数字信号在第一电压和第二电压之间工作,其中第一电压对应于逻辑0,第二电压对应于逻辑1.第二数字信号在第三电压和第四电压之间工作, 电压和第四电压呈现平均值,其绝对值至少是与第一电压和第二电压的平均值不同的数量级。 电路板进一步操作以使用第一数字信号产生第二数字信号。 还提供了方法和其它系统。
