Basic ECG signal processing using MATLAB, including noise filtering, frequency domain analysis, and a custom notch filter to remove 50 Hz noise. This project focuses on basic ECG (Electrocardiogram) ...

frequencies = linspace(0, fs/2, floor(length(ecg_data)/2) + 1); % Positive frequency components % Plotting Frequency Domain Graph of ECG Signal fft_ecg_data = abs(fft ...

Abstract: This paper deals with the analysis of ECG signals using zoom FFT. The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through ...
