Question
Consider an aperiodic continuous-time signal
x(t) having the corresponding Fourier
transform X(jw).
What would be the Fourier transform of the
signal
y(t) = x(t) cos(3лt)
Select one:
O /(X(j(w + 3n) + X(j(w − 3ñ)))
○ ¹⁄(X(j(w + 6ñ) + X(j(w − 6ñ)))
○ 3/7 (X(j(w + 2ñ) + X(j(w − 2ñ)))
3π
○ ½(X(−jw) + X(jw))
○
½(X(j(w + 3ñ) − X(j(w – 3ñ)))
