What is the value of h(M-1/2) if the unit sample response is anti-symmetric?
A. 0
B. 1
C. -1
D. None of the mentioned
Answer:A
What is the value of h(M-1/2) if the unit sample response is anti-symmetric?
A. 0 B. 1 C. -1 D. None of the mentioned
Explanation: When h(n)=-h(M-1-n), the unit sample response is anti-symmetric. For M odd, the center point of the anti-symmetric is n=M-1/2. Consequently, h(M-1/2)=0.
