Hi Hayder,

your coefficients(posted at start of this thread) are ok. I checked them in Matlab and your filter does cutoff at .02 and .07 of sampling frequency (passband is 20/1000 to 70/1000). Your problem is not the design of coefficients(that is done). It is in the implementation. You need to check whats going wrong in your FIR compiler settings.
