摘要：

In this paper the combination of genetic algorithm and a. new variable step-size algorithm. for a second-order adaptive IIR notch filter is presented. The objective of the new algorithm is to optimize the filter. coefficient. The results of computer simulation show that the new algorithm provides a good performance such as fast convergence rate, low mean square error and noise robustness. In additions the new algorithm is also applied to cancel 50-Hz power line interference in the recording of electrocardiograms signal.
