    • Disturbances in bipolar signals transmitted on a transmission line are suppressed by adjusting the amplitude of the signals with coarse adjustment steps and with fine adjustment steps. The amplitude adjusted signals are compared to at least a lower reference level and an upper reference level for determining a first percentage of the amplitude adjusted signals violating the lower reference level and a second percentage of the amplitude adjusted signals violating the upper reference level. The coarse adjustment steps and the fine adjustment steps are selected in accordance with an adjustment characteristic which evaluates at least the first percentage and the second percentage. The adjustment characteristic is changed if a tendency of reference level violation of the amplitude adjusted signals is detected and a check is performed if the step of changing the adjustment characteristic improves the disturbance suppression. A device for suppressing disturbances is also provided.
    • 在传输线上传输的双极信号的干扰通过用粗调整步骤和微调步骤调节信号的幅度来抑制。 将幅度调整信号与至少较低的参考电平和较高的参考电平进行比较,以确定违反较低参考电平的幅度调整信号的第一百分比以及违反上参考电平的幅度调整信号的第二百分比。 根据至少评估第一百分比和第二百分比的调整特性来选择粗调步骤和微调步骤。 如果检测到参考电平违反振幅调整信号的趋势,则改变调整特性,并且如果改变调节特性的步骤改善了干扰抑制,则执行检查。 还提供了用于抑制扰动的装置。
