Abstract :
Power-line interference is a common problem during biopotential measurement. Here an easily implemented algorithm for adaptive power-line interference canceling is presented. The proposed algorithm is based on the iterative update of amplitude, frequency and phase of a sine wave according to the least-mean-squares (LMS) algorithm. The advantage of the proposed technique is no extra reference signal needed during the biopotential measurement
