Aiming at how to prevent periodicinterference, more papers have covered LMS adaptive filter, which needs to adjust many parameters and shows instability in pulse type interference.
We analyze rejecting periodicinterference in PD monitoring on line through cascade IIR digital wave notch filter. The principle and simple design method are proposed and discussed.
