Step 1

Given discrete-time LTI systems are

Step 2

Part (a)-

although

filter co-efficient of H_{1}(z) is -1

filter co-efficient of H_{2}(z) is +0.8

filter co-efficient of H_{3}(z) is -0.8

so, all three discrete-time LTI system have real valued filter co-efficient therefore all have real valued impulse response.

Step 3

Part (b)-

Given Input is, x[n]=1

z-t...
