Explanation: The granular noise occurs w hen the DM tracks a relatively flat (slowly changing) input signal. We note that increasing ∆ reduces overload distortion but increases the granular noise, and vice versa. 14. Which of the following is the right way to reduce distortion in the DM?
A. By setting up an integrator in front of DM
B. By setting up an integrator behind the DM
C. By setting up an integrator in the middle of DM
D. None of the mentioned
Answer:A

Explanation: We note that increasing ∆ reduces overload distortion but increases the granular noise, and vice versa. One way to reduce these two types of distortion is to use an integrator in front of the DM.
