Digital Signal Processing Filter Techniques For Bio Potential Recording System Of Human Visual Optic Nerve Pathway Conduction Measurement Using Visual Evoked Potentials

Abstract

Basically Visual evoked potentials (VEP) are very low potential and it is very difficult to identify the original signal after many times
of amplifications and filtering methods .Due to this problem we need to go for strong extraction tools to develop their originality
reproducible morphology in the clinical laboratories. Normally the test carried out with conventional averaging method to avoid and
cancellation of unwanted signals which is routinely used in hospitals. But there will be a little bit amount of information may lost to
reproduce the original signal after averaging method. For this reason we need to go for adaptive noise cancellation filter techniques
which will be helpful to eliminate the complete background noise and reproducible original signal without any loss of information.
