signal processing in ecg

can you tell me the matlab codes to bandpass the ecg signal to 1-35hz?

[Wayne King]

what is your sampling frequency?

[Kirthika]

sampling frequency is 360...

There are many ways with fdesign.bandpass and if you just remove the mean from the signal, I think you can just use fdesign.lowpass in this application, but here is one way:

    d = fdesign.bandpass( 'N,F3dB1,F3dB2',20,1,35,360);
    Hd = design(d);

Then filter the signal with:

      output = filter(Hd,input);

thanks a lot..will try this..
