This looks like pre-emphasis. The idea is to pre-distort the signal before transmitting it down the cable so that the eye at the far end of the cable is more open. If you check the pre-distorted eye at the transmitter, you'll likely see something like this with lots of overshoot. WebBased on display investigation, one can assess various system performances. Further, an eye diagram is used to analyze the signal state as poor synchronization, long, noisy, short, overshoot, slow, undershoot, etc. Here, signal distortion is caused because of noise and inter-symbol interference by eye patterns.
