The spectrum of an
analog signal is shown below. It is sampled, with an ideal impulse sampler, at
a rate of 200 Hz.
(a) Draw the spectrum of the sampled signal and show the baseband and first two
positive frequency replications with their end frequency values marked. (Hint:
Follow the method outlined in the lecture.)
(b) State below the frequency range of the signal, in baseband, that will
become corrupted and thus unrecoverable because the signal was undersampled.
(Hint: The area of corruption is the area in which baseband and first positive
frequency image overlaps.)
