WebApr 4, 2024 · Python has an in-built ecg database. It makes it more efficient, since we do not need data from an external source. To read this data, we use the code below: x = pywt.data.ecg ().astype (float)/256 # In-built ecg data is read The signal obtained from the database is noise-free. We need to add noise to it to perform the denoising operation. WebApr 19, 2024 · Use the scipy.convolve Method to Calculate the Moving Average for NumPy Arrays. We can also use the scipy.convolve () function in the same way. It is assumed to be a little faster. Another way of calculating the moving average using the numpy module is with the cumsum () function. It calculates the cumulative sum of the array.
