This paper presents a brief documentation about concepts of Electroencephalography (EEG) and it’s one type of artifact i.e. functioning and problems if any, Neurologists uses Electroencephalography technique. But while recording brain signals, noise (Artifact) gets induced and became part of EEG recording. problems for Nero Experts to analyse and interpret it and hence it is necessary to remove such artifact from recordings. Ocular artifact related to Eye movement is in existence which may also resemble to disordered pattern. One can detect and multi resolution analysis of signal is the key idea for identifying typical trends and similar pattern of required frequency band and minimization of their impact. Sufficient information about components of the original signal may be obtained using Discrete Wavelet Transform.Discrete Wavelet functions such asMODWT, IMODWT and MODWTMRA are the used to localize required pattern and remove that from the signal.
