Determine the bandwidth of the following functions, assume f1>>>f2:
a) \(x_{2}(t) = sin(2\pi f_{1}t) + cos(2\pi f_{2}t)\)
Here the bandwidth is zero, because the frequency spectrum of these sinusoids consists of 4 impulses, all of which have no width.
b) \(sin(2\pi f_{1}t)cos^{2}(2\pi f_{2}t)\)
This one I'm not sure about. f1 would be acting as the carrier for the second signal since f1>>>f2 correct?
