| Abstract: | To prevent the biomedical signals from being disturbed by 50Hz noise easily,the paper designs a bandstop digital filter by procedure and FDATool method.The filter is tested by a blended sine wave experimentally and the result shows that the filter can cancel the 50Hz noise very well. |
