Optimum notch filtering
WebJan 1, 2015 · Considering various noise present in the ECG signal in the range 32 to 60 Hz, the center frequency of purposed notch filter is varied in a specified range. The optimized adaptive notch filter automatically search for noise signal present at a particular frequency and achieves a notch filter characteristic at that frequency to eliminate the noise. http://engr.case.edu/merat_francis/eecs490f07/Lectures/Lecture15.pdf
