What is the maximum value of fp with which good designs are obtained for M odd?
A. 0.25
B. 0.45
C. 0.5
D. 0.75
Answer:A
What is the maximum value of fp with which good designs are obtained for M odd?
A. 0.25 B. 0.45 C. 0.5 D. 0.75
Explanation: Designs based on M odd are particularly poor if the bandwidth exceeds 0.45. The problem is basically the zero in the frequency response at ω=π(f=1/2). When fp <0.45, good designs are obtained for M odd.
