摘要：Increased cases of cardiac arrests resulting from coronary heart disease (CHD) underscores the need for accurate equipment for monitoring and diagnosis of the health conditions of hearts of human beings so that proper medical treatment and advice can be given to people who suffer from heart or heart-related diseases. An electrocardiograph is an instrument or equipment for checking heath condition of hearts by measurement of the quality of electrocardiographic (ECG) signal. The ECG signal is usually corrupt by artifacts and these must be removed before the real shape of the signal can be determined. Filters can be used to realize this. This paper therefore presents designs of digital FIR low pass, high pass and notch filters necessary for the removal of the artifacts. Each filter is designed with a rectangular window. Noisy ECG signal is passed through each filter and results are obtained and presented.
