Verified Answer
Increased pulse-width in the flat-top sampling leads to:a)Attenuation ...
Explanation: As pulse width is increased, the width of the first lobe of the spectrum is decreased. Hence, increased pulse-width in the flat-top sampling, leads to attenuation of high frequencies in reproduction.

Effect of Increased Pulse-Width on Flat-top Sampling
Attenuation of High Frequencies in Reproduction
Increasing the pulse-width in flat-top sampling leads to the attenuation of high frequencies in reproduction. This is because, in flat-top sampling, the amplitude of the signal is integrated over the pulse-width. As the pulse-width is increased, the integration time is also increased, which results in the attenuation of high-frequency components of the signal.
Reason for Attenuation of High Frequencies
The attenuation of high frequencies occurs because the integration time is longer than the period of the high-frequency components of the signal. As a result, these high-frequency components are not sampled properly and are attenuated.
Effect of Attenuation on Reproduction
The attenuation of high frequencies in reproduction can lead to distortion of the signal. This is because the high-frequency components are important for the fidelity of the signal. Attenuation of these components can lead to a loss of detail and clarity in the reproduced signal.
Conclusion
In conclusion, increasing the pulse-width in flat-top sampling can lead to the attenuation of high frequencies in reproduction. This can result in distortion and a loss of fidelity in the reproduced signal. Therefore, it is important to carefully choose the pulse-width in flat-top sampling to ensure that the desired frequency components of the signal are properly sampled and reproduced.
