[T F] After sampling process. It is possible to see whether the signal is distorted or not in the time domain. What is the maximum frequency contained in the signal if a sampling rate is given as f_s What is the maximum frequency contained in radians in the signal if a sampling rate is given as f_s What is the period of the signal in the frequency domain in radians? What is the minimum sampling rate must be to prevent signal distortion If sampling rate is not enough what is happening in the sampled signal? What is the magnitude of the pulse train in the frequency domain A frequency response of pulse train is a pulse train in the frequency domain Why does the frequency response become periodic (with one sentence)? What is the sampling rate of compact disc (or CD Is it possible to recover the distorted signal if a distorted signal came from lack of sampling process? In general, how much of maximum frequencies, can a person handle with an ear? What is the amplitude of the pulse train in the time domain? The frequency response of the sampled signal in the frequency domain is continuous

Solution

3) False

4) fs/2

5) pi*fs/2

6) 2*pi/w

7) 2*f

8) distortion

9) f, signal frequency

10) True

11) multiplication in time domain gives convolution in frequency domain

12) 44,100Hz

13) False

14) 20Hz - 20KHz

15) 1

16) False
