function [hx] = formfiltersdwt(n_stages,branch,h0,h1)
if(branch==1)
    hx=formfilters(n_stages,branch,h0,h1);
elseif(branch==2)
    hx=formfilters(n_stages,2,h0,h1);
else
    hx=formfilters(n_stages-branch+2,2,h0,h1);
end

% The code line that is changed in formfilters.m for DWT is:
%p = mod(2^(n_stages-1-i),p);
