Abstract
A Notch Filter is essential in ECG signal processing to eliminate narrowband
noise, especially powerline interference at 50 Hz or 60 Hz. This interference
overlaps with vital ECG signal features, affecting the accuracy of downstream
classification tasks (e.g., arrhythmia detection). A properly designed notch
filter enhances signal quality, preserves essential ECG components (P, QRS, T
waves), and improves the performance of machine learning or deep learning
models used for ECG classification.
