Hello guys.
I have ECG signal with 125 sampling frequency and i have to filter it with low pass filter. Which are the best "settings of filter?"
[b, a] = fir1(%i need 2 arguments here
, 'low');
y = filtfilt(b, a, ECG);
[peaks, poloha] = findpeaks(y, 'MinPeakDistance', 320);
ECG_sprac = length(poloha);
[b, a] = fir1(%i need 2 arguments here
,'low');
y = filtfilt(b, a, PPG);
[peaks, poloha] = findpeaks(y, 'MinPeakDistance', 320);
PPG_sprac = length(poloha);
breathVAL = (ECG_sprac + PPG_sprac)/2;

hi
maybe you should first explain why the need for low pass filterning (noise ?) and also sharing the data would help
