摘要： A slicer can receive a communication signal having a level or amplitude that is between two discrete levels of a multilevel digital communication scheme. The slicer can compare the communication signal to a plurality of references such that multiple comparisons proceed essentially in parallel. A summation node can add the results of the comparisons to provide an output signal set to one of the discrete levels. The slicer can process the communication signal and provide the output signal on a symbol-by-symbol basis. A decision feedback equalizer (“DFE”) can comprise the slicer. A feedback circuit of the DFE can delay and scale the output signal and apply the delayed and scaled signal to the communication signal to reduce intersymbol interference (“ISI”).

摘要翻译：限幅器可以接收具有在多级数字通信方案的两个离散级之间的电平或幅度的通信信号。切片器可以将通信信号与多个参考进行比较，使得多个比较基本上并行进行。求和节点可以添加比较结果，以将输出信号设置为离散电平之一。切片器可以处理通信信号，并在逐个符号的基础上提供输出信号。判决反馈均衡器（“DFE”）可以包括限幅器。 DFE的反馈电路可以延迟和缩小输出信号，并将延迟和缩放的信号应用于通信信号以减少符号间干扰（“ISI”）。
