Abstract
A device that detects an effect which distorts a communication signal in a serial communication channel comprises an input, a detector connected to the input, a demultiplexer having a data input connected to the output of the detector, and an evaluator at each output of the demultiplexer. The input receives the distorted communication signal from the communication channel. The detector detects a feature in a symbol of the distorted communication signal and outputs the detected feature. The demultiplexer outputs the detected feature and has a plurality of control inputs. A differently delayed symbol (i−1, 1, i+1) of the communication signal is applied to each input to switch the detected feature present at the input of the demultiplexer to an output of the demultiplexer specified by the symbols present at the control inputs.
