ESE 351 Quiz 23 Name: 11/30/10 Section 13.1–13.4 a. What is a distortionless transmission? Either give its frequency re- sponse, H ( ω ) or H ( θ ), or explain in English by stating the effects on the amplitude and the phase of the input sinusoid. b. What is an ideal low-pass filter? Either give its frequency response, H ( ω ) or H ( θ ), or explain in English by stating the effects on the am- plitude and the phase of the input sinusoid. c. If U ( ω ) is the Fourier spectrum of the input

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