Question:
Le x(n) be a signal with Fourier transforms as shown in figure. Determine and sketch the Fourier Transforms of the following signals.(a) x1(n) = x(n) cos(?n/4)(b) x2(n) = x(n) sin(?n/2)(c) x3(n) = x(n) cos(?n/2)(d) x4(n) = x(n) cos?nNote that these signal sequences are obtained by amplitude modulation of a carrier cos?0n or sin?0n by the sequence x(n)
