Evaluation of New Methods for Artifacts Rejection in Evoked Auditory Steady-State Potentials

Abstract

This paper presents two alternative methods to the traditional method of artifact rejectionequipment currently used in evoked potential recording steady state (ASSR) in order to improveefficiency based on the use of a larger number of individual records. The first method proposedis to replace the traditional use of rejection threshold amplitude, while the second version is afaster implementation of the weighted averaging used today, which is applicable also in thetransient Auditory Brainstem Response (ABR). These changes have been made in order toimplement these methods in a real time microprocessor.
