Sketch the single-sided and double-sided amplitude and phase spectra of the following signals: (a) x 1 (t)
Question:
Sketch the single-sided and double-sided amplitude and phase spectra of the following signals:
(a) x1(t) = 10 cos(4πt + π/8) + 6 sin(8πt + 3π/4)
(b) x2(t) = 8 cos(2πt + π/3) + 4 cos(6πt + π/4)
(c) x3(t) = 2 sin(4πt + π/8) + 12 sin(10πt)
(d) x4(t) = 2 cos(7πt + π/4) + 3 sin(18πt + π/2)
(e) x5(t) = 5 sin(2πt) + 4 cos(5πt + π/4)
(f) x6(t) = 3 cos(4πt + π/8) + 4 sin(10πt + π/6)
