course : ( signals: continuous and discrete)

0 pts ended
Pick two functions, x1(t) = cos(w1t) and x2(t) = sin(w2t) where w1 and w2 are dierent
frequencies (to make life easy you should probably select these frequencies such that their ratio is a rational number). In other words, take the Fourier Transform co-ecients you calculate by hand and use Matlab to rebuild x(t) using those co-ecients.
x1 = cos(2t) & x2 = sin(4t)
Solve Fourier transform for x1 & x2.
Then multiply both [ X = x1 * x2 ] and take Fourier transform of that.
What is the eect on the Fourier Transform of multiplying the two signals together ?
