It is a cascade form of realization, in which two filter are cascaded one after another.

Where H1(z)=Z+0.55/z+0.57

And H2(z)= z+0.69/z+0.56

Note-please find me in comment box if you find any difficulty. It is cascade realization of filter, hence it is divided into two filter H1(z) and H2(z). Please let me know if you want more information. Good luck
