Modified adaptive line enhancement for evoked potential extraction
Guruprasad Madhavan · 2003
A method called modified adaptive line enhancement (MALE), which is used to obtain evoked potentials with a minimum number of stimulus repetitions, is described. The theory of MALE is developed, and the assumptions made are tested and shown to be adequate in the case of the brainstem auditory evoked potential. The signal distortion is characterized, and a method to alleviate the problem is developed. Using the weighted exact least squares lattice algorithm, the MALE method is implemented and applied to real data.>
