i need the answer quickly
|x (t) - -
X = 26(t + 2) — 28(t − 2) — rect(+¹) +rect (¹¹)
So,
dF(t)
dt
· = F₁ (t) + F₂ (t)
F2
2 (+)... ..... equation 1.
F₁ (w)
Fit replace by F₁w
F₁ (1)
(1) replace by F₂ (w)
F2
Apply Fourier transform,
jw F(w) = F₁ (w) + F2₂(w)...... equation 2
F₁(t) = −6(t + 2) + 6(t - 2)........ equation 3
now t replace by w,
F₁(w) = -2 [+]
F₁(w)
F1(w) = 4jwSin²w.
and
F2(w) = 2 x 4Sin (2)
=
x 2
|F2(w) = 8Sin (²)
F2(w) = -8Sin2w jw
How did he get the
value:
