Web11 jun. 2024 · Photoplethysmography is a bioelectrical signal obtained from regions where the body's capillaries are dense, providing information about flowing blood volume. PPG signals contain a lot of information about the physiological and biological state of the person and are obtained with a lot of noise. In this study, Butterworth, Chebyshev Type I, … Web8 feb. 2016 · Now, a butterworth filter is a recursive thing, so to calculate the next part of your sampled signal, you'll need the last state. That's exactly the "filter delay state zi" that lfilter returns and can take in on the next call as zi parameter. but I don't know how to use it to get a constant signal.
