GATE2017 EC2: 47
A secondorder LTI system is described by the following state equations, $\frac{d}{dt}x_1(t)x_2(t)=0$ $\frac{d}{dt}x_2(t)+2x_1(t)+3x_2(t)=r(t)$ where $x_1(t)$ and $x_2(t)$ are the two state variables and $r(t)$ denotes the input. The output $c(t)$=$x_1(t)$. The system is undamped (oscillatory) underdamped critically damped overdamped

The transfer function of a causal LTI system is $H(s)=1/s$. If the input to the system is $x(t)=[\sin(t)/\pi t] u(t)$, where $u(t)$ is a unit step function, the system output $y(t)$ as t→∞ is ____________
