Multiresoloutional Filtering for Evoked Potential Estimation using Wavelet transform .
Yeganeh Payam, Mohammad Moradi, Reshad Ali · 2001
We would like to propose a method for estimation of evoked potentials (EP) using Multiresoloutional filters based on the wavelet transform (WT) Coefficients. These filters are simply implemented by wavelet transforming of the recorded signal (EP + Noise), selection of some critical coefficients, applying a noise reduction method and inverse wavelet transforming the result coefficients. In this paper we use above procedure for estimation of Brainstem Auditory Response (ABR) and Visual Evoked Potentials (VEP).
