The impulse response of a linear system is (h(t)) (=Aleft[delta(t)-alpha e^{-alpha t} u(t)ight]), with (alpha>0). Let (A=10)

Question:

The impulse response of a linear system is $h(t)$ $=A\left[\delta(t)-\alpha e^{-\alpha t} u(t)ight]$, with $\alpha>0$. Let $A=10$ and $\alpha=3$ and use MATLAB to plot $|H(\omega)|$. On the same axes, plot $|H(\omega)|$ for $A=10$ and $\alpha=6$. Describe the system frequency response and the influence of the parameter $\alpha$.
