GATE EE 1995

MCQ (Single Correct Answer)

-0.3

The impulse response of an initially relaxed linear system is $${e^{ - 2t}}u\left( t \right).$$ To produce a response of $${te^{ - 2t}}u\left( t \right),$$ the input must be equal to

$${2e^{ - 2t}}u\left( t \right)$$

$${1 \over 2}{e^{ - 2t}}u\left( t \right)$$

$${e^{ - 2t}}u\left( t \right)$$

$${e^{ - t}}u\left( t \right)$$
