Unformatted text preview: E. None of the above (200 Hz and 400 Hz) 18. The analytic signal for h(t) in problem 17 consists of: A. Positive and negative frequencies B. Positive and negative frequencies and DC (f=0) C. Positive frequencies only D. Positive frequencies and DC (f=0) E. None of the above 19. You are asked to measure the magnitude of the complex transfer function (H) of an EKG amplifier that has a bandwidth of 500Hz. You connect a white noise source generator to the input of the amplifier and sample the output (vout) at 10 KSamples/sec and record N=1000 samples. You then compute the FFT of vout. Which is the following is true: A. The complex FFT of vout is proportional to the complex transfer function H. B. The magnitude of the FFT of vout is proportional to the complex transfer function H. C. The magnitude of the FFT of vout is proportional to the magnitude of the transfer function H. D. The squared magnitude of the FFT of vout is proportional to the magnitude of the transfer function H. E. None of the above Name: __________________________________ 2...
