Computing 1024 FFT from noisy ecg
5 views (last 30 days)
I am wondering how to compute a 1024 point FFT from an initial 1024 samples segment of a noisy ECG without DC component. Then, from the obtained FFT, plot the absolute value (magnitude) of the frequency spectrum of the noisy ECG (without DC component) expressing the x-axis (horizontal) in units of frequency (Hz)

You can refer to the following link to get examples on how to remove noise from ECG signals.
After removing noise, you can compute the 1024 FFT of the signal using the ‘fft’ function. Refer to the link below for more information on ‘fft’:
