Artifact Removal from ECG Signal Using Notch Filter for Developing Countries

Abstract:

In an increasingly noisy society, methods of reducing noise are becoming more important. Filtering has the great importance in the field of the biomedical signal processing. In many applications of signal processing it is desired to remove sinusoidal interferences while leaving the broadband signal unchanged. Examples are in the areas of communication, control, biomedical engineering and others. A typical one is to cancel 60 Hz power line interference in the recording of electrocardiogram (ECG). Usually this task can be achieved by the notch filters characterized by a unit gain at all frequencies except at the sinusoidal frequencies in which their gain is zero .To eliminate one narrow band of frequencies one uses a so-called "notch" filter (named for the fact that it makes a notch in the frequency spectrum).In this paper we have given a notch filter of cost Rs 200. (4 USD approx.) that’s why it will be very beneficial for developing countries.
