摘要：
A system and method of filtering input data to remove power line interference is disclosed. The system and method estimates the statistics of the input signal and include determining a value (R) from the ratio of a peak amplitude (A peak ) and a root-mean-square of the amplitudes of the interference harmonics (A rms ), calculate a running histogram of the determined value (R) to determine a threshold value (TH R ), comparing the determined value (R) to the determined threshold value (TH R ) to make a decision about feature existence, and outputting a feature decision. The system and method include estimating the interference level to determine if interference is low level or high level. The system and method include estimating interference using the feature detection, amplitude and phase； and removing the estimated interference from the signal to result in a signal substantially free of power line interference.
