% DEFINE FILTER PARAMETERS
Fs = 2E+6;
Fn = Fs/2;
Fc1 = 630;
Fc2 = 640;
Fs1 = Fc1*0.8;
Fs2 = Fc2/0.8;
Rp = 1;
Rs = 10;
% DESIGN FILTER
[n,Wp] = ellipord([Fc1 Fc2]/Fn, [Fs1 Fs2]/Fn, Rp, Rs);
[z,p,k] = ellip(n,Rp,Rs,Wp);
[sos,g] = zp2sos(z,p,k);
figure
freqz(sos, 2^14, Fs)
How to apply the above filter to the file (each row is ecg for 1 person): https://drive.google.com/file/d/1vXb3zY1hlKdXbn6cSvrm7O7OfL1Nx_qe/view?usp=share_link

FilteredRowsOfECG = sosfilt(sos, YourRowsOfECG, 2);
