Solution:
S=2T(1−2−11+2−1)=2(1−z−11+z−1). [2(1−z−11+z−1)+0.1]2+9=2(1−z−1)+0.1(1+z−1)(1+z−1)(2(1−z−1)+0.1(1+z−1))2(1+z−1)2+9
H[z]=[2(1−z−1)+0.1(1+z−1)](1+z−1)[2(1−z−1)+0.1(1+z−1)]2+9(1+z−1)2
By Impulse Invariant method:
H(s)=s+0.1(s+0.1)2+9
The inverse L.T. of the given function is
$ \begin{aligned}\\ h(t) &=e^{-0.1 t} \cos (3 t) & & \text { for } t \geqslant 0 \\\\ &=0 & …
