Solution:
Here given $\Omega_c=1.2 \mathrm{rad} / \mathrm{sec}$.
As sampling frequency is not given
Assume $f_s=1 \mathrm{H}_2$.
$ \omega_c=\frac{2 \Omega_c}{f_s}=1.2 \mathrm{rad} / \text { sample. }\\ $
$ \begin{aligned}\\ h_d[n] &=\frac{1}{2 \pi} \int_{-\pi}^\pi H_d(\omega) e^{j \omega n} d \omega \\\\ &=\frac{1}{2 \pi}\left[\int_{-\pi}^{-1 \cdot 2} e^{j \omega n} d \omega+\left(\int_{1 \cdot 2}^{j …
