Q1:

The function in the given figure can be written as

A
u(t - 1) sin p ( t - 1) - u(t - 3) sin p (t - 3) + u(t - 4) sin p (t - 4) - u(t - 6) sin p (t - 6)

B
u(t - 1) sin p ( t - 1) - u(t - 3) sin p (t - 3) + u(t - 4) sin p (t - 4)

C
u(t - 1) sin p ( t - 1) + u(t - 4) sin p (t - 4)

D
u(t - 1) sin 2p ( t - 1) + u(t - 4) sin 2p (t - 4)

ANS:A -

u(t - 1) sin p ( t - 1) - u(t - 3) sin p (t - 3) + u(t - 4) sin p (t - 4) - u(t - 6) sin p (t - 6)
