Problem $11\mathrm{.}055$: Discrete$-$time systems

Consider the following block diagrams:

Part $3$ of $3$

Problem $11\mathrm{.}055.$e: Discrete$-$time system frequency response

$5$

points

$$

If $a=2\mathrm{.}2988,$ the frequency response is

$H(e^j)=\frac{A{e}^{\frac{j}{2}}-B{e}^j+C{e}^{j2}-D{e}^j+E}{e^4-F{e}^3-G{e}^2+H{e}^j-\text{I}}$

The numerical values of the constants are $A=,B=,C=,D=,E=F=,$ G$=$

$,$ and $I=,H=$
