Signals and Systems - Engineering

Q1:

Assertion (A): L[af1(t) + bf2(t)] = aF1(s) - bF2(s) Reason (R): Initial value theroem enables us to find the value of f(t) at t = 0 directly from F(s)

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is true, R is false

D A is false, R is true

ANS:D - A is false, R is true

£[af1(t) +bf2(t)] = aF1(s) + bF2(s) Hence A is wrong.
