Q1:

The function f(t) in the given figure will have its Laplace transform as

A

B

C

D

ANS:D -

The function is sum of three functions , i.e., a ramp of slpoe 1 originating at t = 0, a ramp of slpoe - 1 Originating at t = 1 and a negative unit step function originating at t = 2, i.e., f(t) = tu(t) - t u(t -1) = u(-2) .
