Ensemble averaging ( ea ) is a conventional method for improving the snr of the recorded vep. depending on the snr of the recorded signal, ea requires 100 - 2000 trials to estimate an ep. targets of others methods are concentrated on decreasing the number of repetitions required and speeding up ep estimation
