The instantaneous sampling
a) Has a train of impulses
b) Has the pulse width approaching zero value
c) Has the negligible power content
d) All of the above
Correct Answer: d) All of the above
The instantaneous sampling is also called ideal sampling or impulse sampling. The instantaneous sampling has a train of impulses. The pulse width of the samples has almost zero value. Therefore it has negligible power content and thus may not be used for transmission purpose.
