Increased pulse-width in the flat-top sampling leads to:
A. Attenuation of high frequencies in reproduction
B. Attenuation of low frequencies in reproduction
C. Greater aliasing errors in reproduction
D. No harmful effects in reproduction
Answer:A
Increased pulse-width in the flat-top sampling leads to:
A. Attenuation of high frequencies in reproduction B. Attenuation of low frequencies in reproduction C. Greater aliasing errors in reproduction D. No harmful effects in reproduction
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.
