Study of sampling theorem, effect of undersampling 
Which of the following is not an advantage of undersampling?
The sampling frequency of the signal g(t) = sinc2 (200 t) is
How many minimum number of samples are required to exactly describe the following signal? x(t) = 10 cos(6πt) + 4 sin(8πt)
A system has a sampling rate of 50,000 samples per second. The maximum frequency of the signal it can acquire to reconstruct is
The spectrum of a band pass signal spans from 20 kHz to 30 kHz. The signal can be recovered ideally from the sampled values when the sampling rate is at least:
