The function in the given figure can be written as
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)
u(t - 1) sin p ( t - 1) - u(t - 3) sin p (t - 3) + u(t - 4) sin p (t - 4)
u(t - 1) sin p ( t - 1) + u(t - 4) sin p (t - 4)
u(t - 1) sin 2p ( t - 1) + u(t - 4) sin 2p (t - 4)
