Abstract

Power-Line interference is a common phenomena is low-frequency biophysical measurement. The usual ways of solving this is the used of fixed bandwidth in analog or digital notch filter. However, these methods are not very suitable for the power-line interference frequency is non-stationary. In this paper, an effective adaptive filter structure is proposed to minimize the residual power-line interference without lost of reality. In order to obtain a satisfactory and acceptable convergence performance, WHT transform is used in the ADF. Throughout many clinical measurements, the result of this structure is effective in eliminating EMI/EMC interference.
