I am trying to use Matlab to analyse this raw signal by introducing Dc-offset analysis:

I used the following code :
a = [1 , -0.98]; b = [1,-1];
y = filtfilt(b,a,x);

And the result :

But, I am trying to get a final result similar to the last graph,
Can you please tell methe exact code to achieve this:

Thank you very much
