Question

The Laplace transform of a parabolic signal is _______

(a) 1

(b) A/s^3

(c) A/s^2

(d) A/s

Answer 1

Correct option is (a) 1

For explanation: As u(t) is a unity step function r(t)=0;t<0 and r(t)=1; t=0. The parabolic signal is a signal which has varying amplitudes and when we take Laplace Transform of that we get 1 as the answer.
