A researcher requires a frequency-domain filter to remove periodic artifacts such as power-line interference on the acquired ECG signal from a patient. What would be a suitable filter design in each of the following conditions. (a) An ECG signal contaminated with a power-line interference at an interference frequency of fo=60 Hz. (Plot your recommended filter magnitude response in dB by hand). Design of Frequency-Domain Filter to Remove Power-Line Interference from an ECG Signal

A Frequency-Domain filter is designed to remove power-line interference from the ECG signal

Frequency-domain filters can be employed in ECG signal processing. They are used to remove power-line interfering. A notch filter is the best type of filter to remove power line interference from an ECG signals. It is a band-stop filter that reduces frequencies. A notch filter’s frequency is determined by power-line interference. This frequency is typically between 50-60 Hz in Europe and the United States (Yeo, et. al. 2017). When designing the notch filter to remove power-line interference from an ECG signal, it is important that the signal-to noise ratio is taken into account. The filter will filter out frequencies within the fo range (Hauser, et. al. 2020). The filter must have a low passband, because a large ripple can cause signal distortion. Finally, the filter’s stopband attenuation should be maximized in order to remove as much of the power-line interference as possible (Bhaskar et al., 2019). Cont….
