Reconstructing band-limited signal's integral from discrete samples [closed]
  1. Which of the following filter is preferred to recover the band limited signal from its samples options?
  2. Why do we need to transmit bandlimited signal?

Which of the following filter is preferred to recover the band limited signal from its samples options?

You can recover a signal from its sampled version by using a lowpass filter to isolate the original spectrum, and cutting (attenuating) everything else.

Why do we need to transmit bandlimited signal?

"why band-limit a signal?" There will be components of a system that have bandwidth limitations. For example, ADCs have a limit as to how fast they can sample. Therefore the frequency content would need to be limited otherwise you would get aliased frequencies.
