A z-plane pole-zero plot for a certain digital filter is shown in figure. The filter has unity gain at dc.(a) Determine the system function in the form, given numerical values for the parameters A, a1, b1, b2, c1, d1, and d2.(b) Draw block diagrams showing numerical values for path gains in the following forms(1) Direct form II (canonic form)(2) Cascade form (make each section canonic, with realcoefficients)
