WebAnswer : The eye pattern is data bits acquired on the display overlaid one on top of each other. Using this technique allows for a quick study of most of the data characteristics. When a pseudorandom data stream is displayed as an eye pattern, the overall quality and stability of the communications system can be observed. Data-stream problems ... In telecommunication, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rate is used to trigger the horizontal sweep (x-axis).
