GATE Electrical 2017 Set 1 | Question: 30
Let a causal LTI system be characterised by the following differential equation, with initial rest condition $\frac{d^{2}y}{dt^{2}}+7\frac{dy}{dt}+10y (t)=4x(t)+5\frac{dx(t)}{dt}$ where, $x(t)$ and $y(t)$ are the input and output respectively. The impulse response of the system ... $7e^{-2t}u(t)-2e^{-5t}u(t)$ $-7e^{-2t}u(t)+2e^{-5t}u(t)$
