The impulse response of an initially relaxed linear system is e-2tu(t) . To produce a response te-2tU(t), the input must be equal to __________ .
e-2t U(t)
e-lt U(t)
e-1u(t)
Answer: Option
Explanation:
Given, h(t) = e-2tu(t) H(s) = 
y(t) = te-2t, u(t) y(s) = 
Using Laplace Transform
∴ x(t) = e-2tu(t)
Input must be equal to e-2tu(t).
