Question

The impulse response of the system shown in figure is,

• A. $h\left(t\right)=sintu\left(t\right)$
• B. $h\left(t\right)=(e^t+e^{-t})u\left(t\right)$
• C. $h\left(t\right)=t^{2}u\left(t\right)$
• D. $h\left(t\right)=e^{-t}u\left(t\right)$

Answer 1

The correct option is A $h\left(t\right)=sintu\left(t\right)$


$H\left(s\right)=\frac{\frac{1}{s^2}}{1+\frac{1}{s^2}}=\frac{1}{s^2+1}$

$h\left(t\right)=sintu\left(t\right)$
