MCQ (Single Correct Answer)

-0.6

The unit impulse response of a system is given as $$c\left( t \right) = - 4{e^{ - t}} + 6{e^{ - 2t}}.\,\,\,$$ The step response of the same system for $$\,t \ge 0$$ is equal to

$$ - 3{e^{ - 2t}} - 4{e^{ - t}} + 1$$

$$ - 3{e^{ - 2t}} + 4{e^{ - t}} - 1$$

$$ - 3{e^{ - 2t}} - 4{e^{ - t}} - 1$$

$$ 3{e^{ - 2t}} + 4{e^{ - t}} - 1$$
