Create an IIR lowpass filter to filter noise on the PPG waveform data (PPGDATA.xlsx). The data was sampled at 2.5 KHz. Choose any order and use a Chebyshev or Butterworth filter. Try to set up the filter order and cutoff such that most of the features are seen on the PPG with as little noise as possible. Below is an example figure (zoomed in) of a filtered PPG. Example PPG 0.15 0.1 0.05 0.05 0.8 0.9 11 12 1314 1.5 Time(s) Only turn in the MATLAB code Create an IIR lowpass filter to filter noise on the PPG waveform data (PPGDATA.xlsx).
