Consider the signal z3(t) = (1+cos(at))sinc(t). The modulated signal s(t) is obtained by multiplying 33(t) by the sinusoidal carrier 10 cos(4nt). Compute the Fourier transforms of r3(t) and s(t). Plot, on four plots on the same figure, z3(t), s(t), X3(w), and S(w). You will need to experiment to choose reasonable values for the time and frequency intervals and increments.
