I will help you design a filter for your data, but I need a sample of it first. I would use a bandpass filter, so I could simultaneously filter out the baseline drift and high-frequency noise.
If it is not stated or available in your signal record (a .mat file is preferable), I will need your uniform sampling interval ‘Ts’ or sampling frequency ‘Fs’. I would of course want the units, but I would anticipate the time variable in seconds or fractions of seconds, and the BP in Torr or mm Hg. I will do my best do explain my filter design choices and code.
