Increased pulse-width in the flat-top sampling, leads to

Attenuation of high frequencies in reproduction
Attenuation of low frequencies in reproduction
Greater aliasing errors in reproduction
No harmful effects in reproduction

The correct answer is C. Greater aliasing errors in reproduction.

When a signal is sampled, the samples are taken at discrete points in time. If the sampling rate is too low, then the samples will not be able to accurately represent the original signal. This can lead to aliasing, which is a distortion of the signal.

The amount of aliasing that occurs is proportional to the width of the sampling pulse. A wider pulse will result in more aliasing errors.

Therefore, increased pulse-width in the flat-top sampling leads to greater aliasing errors in reproduction.

Here is a more detailed explanation of each option:

  • Option A: Attenuation of high frequencies in reproduction. This is not the correct answer because increased pulse-width in the flat-top sampling does not lead to attenuation of high frequencies. In fact, it can lead to an increase in high frequencies.
  • Option B: Attenuation of low frequencies in reproduction. This is also not the correct answer because increased pulse-width in the flat-top sampling does not lead to attenuation of low frequencies. In fact, it can lead to an increase in low frequencies.
  • Option C: Greater aliasing errors in reproduction. This is the correct answer because increased pulse-width in the flat-top sampling leads to greater aliasing errors.
  • Option D: No harmful effects in reproduction. This is not the correct answer because increased pulse-width in the flat-top sampling can lead to harmful effects in reproduction, such as aliasing.
