Eye Diagram Explorer

Overlay pulse-shaped NRZ symbol periods to see the eye opening at each ideal sampling instant.

Binary sequence 4–64 bits; spaces and line breaks are optional

0 maps to −1 and 1 maps to +1. Raised-cosine pulses are truncated six symbols on each side. This ideal educational model includes no noise, jitter or channel loss.
