28 Eye Diagram
28.1 Overview
An eye diagram is an oscilloscope display in which a high-speed digital signal is repetitively sampled
and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is called
an Eye because the pattern looks like a series of eyes between a pair of rails. The combined effects of
channel and dispersion can be evaluated from the Eye opening width and height.
