Amplitude Modulation Consider the signal y ( t ) = cos(2 πf c t ) u ( t ) where w ( t ) = cos(2 πf c t ) is the carrier signal, and u ( t ) is the modulating signal. u ( t ) has spectrum (Fourier transform) as shown below: U(f) f f B -f B The carrier frequency, f c , is much greater than the bandwidth, f B , of the modulating signal. Sketch the transform of the signal y ( t ) on a 3 × 5 card.
