Features of VEP modulations: t-VEP, f-VEP and, c-VEP.

VEP modulation	Features
t-VEP	– Relatively low information transfer rate (<30 bits/min) – Synchronous signal is necessary – No user training required
f-VEP	– High information transfer rate (30–60 bits/min) – Simple system configuration – No user training required – More suitable for application with few options
c-VEP	– Very high information transfer rate (>100 bits/min) – Synchronous signal is necessary – User training required – More suitable for application with many options
