Description
Plot the eye diagram of a synchronous data signal, which is a scatter plot of the signal where the time domain is considered modulo the symbol period (actually using a trigger on the signal, to account for symbol period variations).
This diagram is useful to view the impact of ISI (Inter-Symbols Interferences).
