Design of Digital Filter on ECG Signal Processing

摘要

The ECG signal detected by the body-surface electrode is usually accompanied by baseline drift and power frequency interference etc. So in order to get the ECG signal without excessive distortion, filtering removes interference before analyzing data. This paper details a simple integer coefficient digital filter with IIR structure for FIR, which is band-stop simple integer coefficient digital filter. The design of this paper can be used to filter out the baseline drift and power frequency interference, and ECG signal without analysis.
