MCQ (Single Correct Answer)

-0.6

A system is described by the following differential equation, where $$u(t)$$ is the input to the system and $$y(t)$$ is the output of the system. $$$\mathop y\limits^ \bullet \left( t \right) + 5y\left( t \right) = u\left( t \right)$$$

When $$y(0)=1$$ and $$u(t)$$ is a unit step function, $$y(t)$$ is

$$0.2 + 0.8{e^{ - 5t}}$$

$$0.2 - 0.2{e^{ - 5t}}$$

$$0.8 + 0.2{e^{ - 5t}}$$

$$0.8 - 0.8{e^{ - 5t}}$$
