1. Introduction - NuWrite
A 1-10 Hz bandpass filter was ultimately used to smooth the final curve on which peaks were detected as local maxima. Use of a fourth order Butterworth 60 Hz bandstop filter made the ECG considerably less noisy (Figure 8a) and removed the 60 Hz peak on the PDS (Figure 8b). ... Read Document
