Unformatted text preview: u ( t ) and H ( ω ) is the frequency response of the system, then what is the Fourier spectrum Y ( ω ) of the output y ( t )? d. If F ( ω ) is the Fourier spectrum of f ( t ), then what is the Fourier spec-trum G ( ω ) of g ( t ) = f ( t ) cos ω t ? e. Does the AM radio transmission in the US relies on the synchronous demodulation or the envelope demodulation or neither?...
