Electroencephalograph is electrical activity of brain which is small in amplitude(5 uV to 200 uV). Evoked potentials (EPs) are bioelectric signals generated by the central nervous system (CNS) when it is stimulated by a well-defined external stimulus. EP’s are vey much useful in the diagnosis of visual diseases. Due to very low amplitude of EP as compared to EEG, they are hardly seen in EEG. Many algorithms have been proposed till now for the estimation of EP. A scheme is proposed named subband latency corrected average using uniform filter bank and non-uniform filter bank. The scheme is tested on healthy VEP samples and results are compared with the other schemes as ensemble average and latency corrected average. Better results are achieved compared to other schemes by limiting the frequency band as compared to full frequency band. These techniques need to be tested on the data obtained in different diseased conditions also for other EP signals like Auditory evoked potential and somatosensory evoked responses.
